The author of the article were Izumi, Saika; Nyga, Aleksandra; de Silva, Piotr; Tohnai, Norimitsu; Minakata, Satoshi; Data, Przemyslaw; Takeda, Youhei. The article conveys some information:

A new thermally activated delayed fluorescence (TADF)-displaying macrocyclic compound m-1 comprising of two electron-donors (N,N’-diphenyl-m-phenylenediamine) and two electron-acceptors (dibenzo[a,j]phenazine) has been synthesized. The macrocycle developed herein is regarded as a regioisomer of the previously reported TADF macrocycle p-1, which has two N,N’-diphenyl-p-phenylenediamines as the donors. To understand the influence of the topol. of the phenylenediamine donors on physicochem. properties of TADF-active macrocycles, herein the mol. structure in the single crystals, photophys. properties, electrochem. behavior, and TADF properties of m-1 have been investigated compared with those of p-1. The substitution of p-phenylene donor with m-phenylene donor led to distinct pos. solvatoluminochromism over the full visible-color range, unique oxidative electropolymerization, and slightly lower contribution of TADF, due to the lower CT character in the excited states.

Quality Control of 1-Bromo-3-iodobenzeneIn 2019 ,《Shape-Persistent π-Conjugated Macrocycles with Aggregation-Induced Emission Property: Synthesis, Mechanofluorochromism, and Mercury(II) Detection》 was published in ACS Applied Materials & Interfaces. The article was written by Liu, Yi; Lin, Fa Xu; Feng, Yang; Liu, Xiaoqing; Wang, Lei; Yu, Zhen-Qiang; Tang, Ben Zhong. The article contains the following contents:

Shape-persistent conjugated macrocycles are fundamentally important because of their unique structure and properties. Herein, a series of π-conjugated macrocycles with a shape-persistent architecture, an adaptive backbone, and aggregation-induced emission (AIE) properties are synthesized via oxidative coupling of acetylene-terminated tetraphenylethylene precursor with a half-ring topol. and following transformation from butadiynylene linkers into thienylene ones. Characterization by NMR spectroscopy and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry provided unambiguous proofs for the macrocyclic structures. In particular, the free rotation of aromatic rings in the rigid macrocyclic backbone was validated by two-dimensional NMR spectroscopy, variable-temperature NMR measurements, and theor. calculations Moreover, these shape-persistent macrocyclic chromophores all exhibited obvious AIE phenomena and remarkable mechanofluorochromism behaviors with a red-shifted luminescence upon grinding and blue-shifted emission after solvent annealing. Also, the introduction of S atoms into the macrocyclic frameworks endowed the macrocyclic luminogen the capability to selectively detect mercury(II) ions in aqueous media among other metal ions.

The title of the article was 《The Effects of Ring Strain on Cyclic Tetraaryl[5]cumulenes》.Reference of 1-Bromo-3-iodobenzene The author mentioned the following in the article:

Cyclic tetraaryl[5]cumulenes I (n = 1, 2, 3, 4, 5, 6) have been synthesized and studied as a function of increasing ring strain. The magnitude of ring strain is approximated by the extent of bending of the cumulenic core as assessed by a combination of X-ray crystallog. anal. and DFT calculations In particular, the exptl. HOMO-LUMO gap is not appreciably affected by bending of the [5]cumulene framework from ca. 174°λmax = 504 nm in I (n = 1) to ca. 178° λmax = 494 nm in I (n = 6).

And the article was published in ACS Applied Materials & Interfaces in 2019. Formula: C6H4BrI The author mentioned the following in the article:

A novel, efficient, deep-blue fluorescent emitter mPAC, with a meta-connected donor-acceptor structure containing phenanthroimidazole (PPI) as the donor and phenylcarbazole-substituted anthracene (An-CzP) as the acceptor, was designed and synthesized. The meta-linkage provided a highly twisted mol. conformation, which efficiently interrupts the intramol. π-conjugation, resulting in a deep-blue emission. The optimized nondoped device based on mPAC displayed a deep-blue emission with a narrow full width at half-maximum of 56 nm and Commission Internationale de L’Eclairage coordinates of (0.16, 0.09). The maximum external quantum efficiency (EQEmax) is 6.76%, corresponding to a high exciton utilization efficiency (EUE) of 59.3-88.9%. Exptl. results and theor. anal. indicated that the high EUE is mainly ascribed to the reverse intersystem crossing (RISC) from T2 to S1, a “”hot exciton”” path in which the large T2-T1 energy gap (1.45 eV) and small T2-S1 energy difference (0.18 eV, T2 > S1) hamper the internal crossing from T2 to T1 and facilitate the RISC process. For the hot exciton path, the T2 state can be feasibly arranged to a high energy level, forming a thermal equilibrium with S1, even slightly higher than the deep-blue S1 to realize an exergonic RISC process, which is usually difficult for the thermally activated delayed fluorescence emitters.

The author of 《Synthesis, characterization and optical properties of novel Ir(III) complexes bearing N-heterocycle substituents》 were Tang, Meng; Zhu, Senqiang; Liu, Rui; Wang, Jia; Zhang, Zheng; Zhu, Hongjun. And the article was published in Journal of Organometallic Chemistry in 2019. Reference of 1-Bromo-3-iodobenzene The author mentioned the following in the article:

A series of cationic heteroleptic Ir(III) complexes with different N-heterocycle groups (N-phenothiazinyl, N-indolyl, N-carbazolyl, 3,6-di-tert-butyl-N-carbazolyl) (1a-1d) were synthesized and characterized. The photophys. properties of these complexes were systematically investigated. All complexes exhibit strong 1π-π* absorption bands in the UV region and broad 1MLCT absorption bands in the visible region. In addition, these complexes exhibit weak absorption after 500 nm, which could be attributed to 3π,π*/3CT transition. All complexes exhibit broad and structureless emission bands from 568 nm to 627 nm at room temperature, which are originated from 3MLCT/3LLCT excited states. The electron donating substituents attached on the 2-phenylpyridine ligands cause a pronounced red-shift of the emission band. Except 1d, all complexes show strong triplet transient absorptions from UV to visible region, which were assigned to the 3MLCT/3π,π* excited state. In addition, complexes 1a-1c all exhibit reverse saturable absorption (RSA) at 532 nm, which follows the trend of 1a > 1b > 1c. The photophys. properties of these Ir(III) complexes can be influenced drastically by the substituents on 2-phenylpyridine ligands, which would be useful for rational design of optical functional materials. In the part of experimental materials, we found many familiar compounds, such as 1-Bromo-3-iodobenzene(cas: 591-18-4Reference of 1-Bromo-3-iodobenzene)

《Double carbonylation of iodoarenes in the presence of a pyridinium SILP-Pd catalyst》 was written by Urban, Bela; Nagy, Eniko; Nagy, Petra; Papp, Mate; Skoda-Foldes, Rita. Recommanded Product: 591-18-4 And the article was included in Journal of Organometallic Chemistry in 2020. The article conveys some information:

The efficiency of a palladium catalyst, immobilized on a supported ionic liquid phase (SILP) with adsorbed 1-butyl-4-methylpyridinium chloride, was investigated in aminocarbonylation reactions. Double carbonylation was found to be the main reaction using different iodoarenes and aliphatic amines as substrates. Application of aniline derivatives as nucleophiles led to the exclusive formation of substituted benzamides. The stabilization effect of the adsorbed pyridinium ionic liquid was compared to that of imidazolium and phosphonium derivatives It was proved that the pyridinium SILP-palladium catalyst could be reused in at least 10 cycles. Recyclability was tested in five successive runs for all of the substrates. The results came from multiple reactions, including the reaction of 1-Bromo-3-iodobenzene(cas: 591-18-4Recommanded Product: 591-18-4)

In 2019,Advanced Materials (Weinheim, Germany) included an article by Xu, Yuwei; Liang, Xiaoming; Zhou, Xuehong; Yuan, Peisen; Zhou, Jiadong; Wang, Cong; Li, Binbin; Hu, Dehua; Qiao, Xianfeng; Jiang, Xiaofang; Liu, Linlin; Su, Shi-Jian; Ma, Dongge; Ma, Yuguang. Name: 1-Bromo-3-iodobenzene. The article was titled 《Highly Efficient Blue Fluorescent OLEDs Based on Upper Level Triplet-Singlet Intersystem Crossing》. The information in the text is summarized as follows:

Purely organic electroluminescent materials, such as thermally activated delayed fluorescent (TADF) and triplet-triplet annihilation (TTA) materials, basically harness triplet excitons from the lowest triplet excited state (T1) to realize high efficiency. Here, a fluorescent material that can convert triplet excitons into singlet excitons from the high-lying excited state (T2), referred to here as a “”hot exciton”” path, is reported. The energy levels of this compound are determined from the sensitization and nanosecond transient absorption spectroscopy measurements, i.e., small splitting energy between S1 and T2 and rather large T2-T1 energy gap, which are expected to impede the internal conversion (IC) from T2 to T1 and facilitate the reverse intersystem crossing from the high-lying triplet state (hRISC). Through sensitizing the T2 state with ketones, the existence of the hRISC process with an ns-scale delayed lifetime is confirmed. Benefiting from this fast triplet-singlet conversion, the nondoped device based on this “”hot exciton”” material reaches a maximum external quantum efficiency exceeding 10%, with a small efficiency roll-off and CIE coordinates of (0.15, 0.13). These results reveal that the “”hot exciton”” path is a promising way to exploit high efficient, stable fluorescent emitters, especially for the pure-blue and deep-blue fluorescent organic light-emitting devices. After reading the article, we found that the author used 1-Bromo-3-iodobenzene(cas: 591-18-4Name: 1-Bromo-3-iodobenzene)
