On September 30, 2019, Chhanda, Sadia Afrin; Itsuno, Shinichi published an article.Computed Properties of 144970-30-9 The title of the article was Design and synthesis of chiral hyperbranched polymers containing cinchona squaramide moieties and their catalytic activity in the asymmetric Michael addition reaction. And the article contained the following:

Chiral hyperbranched polymers (HBP) containing cinchona alkaloids were synthesized using a Mizoroki-Heck (MH) coupling polymerization reaction between a cinchona squaramide dimer and tri- or tetra-substituted aromatic iodides. This was a new type of polymeric chiral organocatalyst. We found that the as-obtained chiral HBPs show excellent catalytic activity in the asym. Michael reaction. Almost perfect enantioselectivity (>99% ee) was achieved in the reaction of β-ketoester and trans-β-nitrostyrene. The three-dimensional network structure of the chiral HBPs is structurally robust and can be reused for further reaction without any loss in their catalytic activity. The experimental process involved the reaction of 1,3,5,7-Tetrakis(4-iodophenyl)adamantane(cas: 144970-30-9).Computed Properties of 144970-30-9

On September 13, 2004, Wei, Qian; Galoppini, Elena published an article.Name: 1,3,5,7-Tetrakis(4-iodophenyl)adamantane The title of the article was Tripodal Ru(II) complexes with conjugated and non-conjugated rigid-rod bridges for semiconductor nanoparticles sensitization. And the article contained the following:

Three tripodal Ru(II)-polypyridyl complexes were synthesized as models to study long-range electron transfer in TiO2 semiconductor nanoparticle thin films, in particular to study the effect of the conjugation of the bridge containing the Ru complex and for distance-dependence studies. The tripodal sensitizers, which are 1,3,5,7-tetraphenyladamantane derivatives having three COOMe anchoring groups and one rigid-rod bridge substituted with a Ru(II) complex, are the longest prepared to date (Ru-to-footprint distance ∼24 Å). Two have a rigid-rod bridge made of two p-ethynylphenylene units (Ph-E)2 capped with a 4-(2,2′-bipyridyl) (bpy) ligand or a 5-(1,10-phenanthrolinyl) (phen) ligand for the Ru complex. The third tripod, which contains a bpy ligand for the Ru complex, has one bicyclo[2.2.2]octylene (Bco) unit in place of a p-phenylene (Ph) unit and is the first example of a tripodal sensitizer with a nonconjugated bridge. Solution absorption and fluorescence data of the three complexes are reported. Photophys. studies of the non-conjugated Bco-bridged complex on TiO2 are not reported. The experimental process involved the reaction of 1,3,5,7-Tetrakis(4-iodophenyl)adamantane(cas: 144970-30-9).Name: 1,3,5,7-Tetrakis(4-iodophenyl)adamantane

W. published an article.Category: iodides-buliding-blocks The title of the article was Nanoscale 1,3,5,7-Tetrasubstituted Adamantanes and p-Substituted Tetraphenyl-methanes for AFM Applications. And the article contained the following:

Tetrahedrally shaped mols.such as I based on tetrasubstituted methane or tetrasubstituted adamantane cores are prepared as potential precursors for single-mol. AFM tips. 1,3,5,7-Tetra(4-iodophenyl)adamantane is prepared in two steps from 1-bromoadamantane and benzene by heating with tert-Bu bromide and aluminum chloride followed by electrophilic iodination; the corresponding tetra(4-iodophenyl)methane is prepared from 4-tritylaniline by diazotization and substitution with iodide followed by electrophilic iodination. N-alkynylaryldithiazepane building blocks are prepared from 4-iodoaniline by addition of ethylene oxide, chlorination of the 2-hydroxyethylamino substituents, conversion via the bisthiocyanate to the dithiazepane, Sonogashira coupling reaction of the aryl iodide moiety with trimethylsilylacetylene and desilylation, coupling with 4-iodophenylethynyltrimethylsilane, and desilylation to provide the arms of I in seven steps.

Boldog, Ishtvan; Domasevitch, Konstantin V.; Baburin, Igor A.; Ott, Holger; Gil-Hernandez, Beatriz; Sanchiz, Joaquin; Janiak, Christoph published an article in 2013, the title of the article was A rare alb-4,8-Cmce metal-coordination network based on tetrazolate and phosphonate functionalized 1,3,5,7-tetraphenyladamantane.Recommanded Product: 144970-30-9 And the article contains the following content:

Sym. tetrahedral ligands are prominent, but somewhat under-studied building blocks for the generation of coordination polymeric networks. Coordination networks [Mn5Cl2(L1)2(H2O)4(DMF)4]·3H2O·7DMF, 1 and the [La2(H5L2)2(H2O)6], 2 were synthesized under mild solvothermal methods in DMF from the adamantane-based tetrahedral ligands, 1,3,5,7-tetrakis(4-phenyltetrazol-5-yl)adamantane (H4L1), reported for the first time, and 1,3,5,7-tetrakis(4-phenylphosphonic acid)adamantane (H8L2), resp. Compounds 1 and 2 are based on completely different pentanuclear and binuclear secondary metal building units, resp., and have different symmetries, but demonstrate an interesting coincidence of underlying topologies, which could be interpreted as a directing or imprinting’ effect of the symmetry of the rigid tetrahedral ligands. Both structures represent examples of a rarely observed (4,8)-coordinated net. The χMT product for 1 at room temperature is slightly lower than the expected for five Mn(II) ions with S = 5/2 and g ≈ 1.98 and on lowering the temperature χMT approaches the expected value for a single Mn(II) as a result of the antiferromagnetic coupling through the tetrazolate bridges.

On July 3, 2002, Galoppini, Elena; Guo, Wenzhuo; Zhang, Wei; Hoertz, Paul G.; Qu, Ping; Meyer, Gerald J. published an article.Recommanded Product: 144970-30-9 The title of the article was Long-range electron transfer across molecule-nanocrystalline semiconductor interfaces using tripodal sensitizers. And the article contained the following:

Four tripodal sensitizers, Ru(bpy)2(Ad-tripod-phen)2+ (1), Ru(bpy)2(Ad-tripod-bpy)2+ (2), Ru(bpy)2(C-tripod-phen)2+ (3), and Ru(bpy)2(C-tripod-bpy)2+ (4) (bpy = 2,2′-bipyridine; phen = 1,10-phenanthroline; Ad-tripod-bpy (phen) and C-tripod-bpy (phen) = tripod-shaped bpy (phen) ligands based on 1,3,5,7-tetraphenyladamantane and tetraphenylmethane, resp.), have been synthesized and characterized. The tripodal sensitizers consist of a rigid-rod arm linked to a RuII-polypyridine complex at one end and three COOR groups on the other end that bind to metal oxide nanoparticle surfaces. The excited-state and redox properties of solvated and surface-bound 1-4 have been studied at room temperature The absorption spectra, emission spectra, and electrochem. properties of 1-4 in acetonitrile solution are preserved when 1-4 are bound to nanocrystalline (anatase) TiO2 or colloidal ZrO2 mesoporous films. This behavior is indicative of weak electronic coupling between TiO2 and the sensitizer. The kinetics for excited-state decay are exponential for 1-4 in solution and are nonexponential when 1-4 are bound to ZrO2 or TiO2. Efficient and rapid (kcs > 108 s-1) excited-state electron injection is observed for 1-4/TiO2. The recombination of the injected electron with the oxidized RuIII center is well described by a second-order kinetic model with rate constants that are independent of the sensitizer. The sensitizers bound to TiO2 were reversibly oxidized electrochem. with an apparent diffusion coefficient ∼1 × 10-11 cm2-s-1. Caution preparation of diazomethane (in synthesis of reactant for preparation tripodal ligand) was done in special glassware with smooth joints following safety precautions.

On February 3, 2016, Patil, Komal M.; Dickinson, Michelle E.; Tremlett, Thomas; Moratti, Stephen C.; Hanton, Lyall R. published an article.Category: iodides-buliding-blocks The title of the article was Synthesis of Diamondoid and Lonsdaleite Networks from the Same Ag(I)-Ligand Combination, with Lonsdaleite the Softer Network. And the article contained the following:

The design and synthesis of a Lonsdaleite (lon) network is an attractive and challenging supramol. target. The authors’ reticular synthesis strategy of slow diffusion of solutions of a simple rigid tetrahedral ligand and a Ag(I) metal ion, at room temperature and atm. pressure, resulted in both lon-MOFs and diamondoid (dia-MOFs) and associated 2D honeycomb networks. The prepared complexes are {[AgL]X.nCH3NO2} [X = CF3SO3-, n = 4 (1a, 1); BF4-, n = 3 (1b, 2); CF3CO2-, n = 5.5 (1c, 3); BF4-, n = 4 (1d, 4)] and interpenetrated dia {[AgL]X.nH2O} [X = PF6-, n = 2 (2a, 5); BF4-, n = 3 (2b, 6); ClO4-, n = 2 (2c, 7), CF3SO3- (2d, 8)] networks along with their associated 2D honeycomb (hcb) networks {[AgL](CF3SO3).2CH3NO2.H2O} (3a, 9) and {[AgL(NO3)].4CH3NO2.H2O} (3b, 10) (where L = tetrakis(4-cyanophenyl)adamantane). Solvent appeared to play a key role in templating the formation of these related networks. Nanoindentation studies show that a dia-MOF was 42% harder than a lon-MOF counterpart. The lon-MOFs were thermally stable and retained integrity until 370° while dia-MOFs exhibited stepwise collapse after initial loss of solvents. As lon networks are often only qual. identified, Cremer-Pople ring puckering anal. was used to quantify the degree of distortion in the lon and related 4-connected 66 networks. The experimental process involved the reaction of 1,3,5,7-Tetrakis(4-iodophenyl)adamantane(cas: 144970-30-9).Category: iodides-buliding-blocks

On November 21, 1994, Reichert, Veronica R.; Mathias, Lon J. published an article.Application In Synthesis of 1,3,5,7-Tetrakis(4-iodophenyl)adamantane The title of the article was Expanded Tetrahedral Molecules from 1,3,5,7-Tetraphenyladamantane. And the article contained the following:

The goal of this paper was to investigate the effects of rigid tetrahedral cores (such as adamantane) on the properties of aramid and poly(phenylene) dendrimers as well as dendrimers that form single mol. micelles. This paper deals with model compound studies dealing with generating tetrasubstituted derivatives of adamantane. A previously reported procedure (for making tetraphenyladamantane) using tert-Bu bromide-AlCl3 catalyzed arylation of 1-bromoadamantane was found not to be a general synthetic method for the preparation of other substituted adamantane derivatives Adamantane derivatives with multiple Ph substituents were isolated only when benzene and bromobenzene were used in the Friedel-Crafts reaction. Tetraphenyl-substituted adamantane derivatives were formed, however, by the traditional Friedel-Crafts arylation of 1,3,5,7-tetrabromoadamantane with bromobenzene and 1,3-dibromobenzene. A lack of regioselectivity for these reactions (isolated mixtures of the meta/para isomers or ortho/meta isomers) was observed Large quantities (50-100 g) of 1,3,5,7-tetraphenyladamantane (1) were prepared from 1-bromoadamantane using a slightly modified literature procedure. This organic insoluble compound was iodinated with [bis(trifluoroacetoxy)iodo]benzene to give the all-para-substituted compound, 5. Compound 5 was further reacted to give numerous derivatives and used as a core in the synthesis of first generation dendrimers. The experimental process involved the reaction of 1,3,5,7-Tetrakis(4-iodophenyl)adamantane(cas: 144970-30-9).Application In Synthesis of 1,3,5,7-Tetrakis(4-iodophenyl)adamantane
