On December 23, 2015, Myahkostupov, Mykhaylo; Castellano, Felix N. published an article.COA of Formula: C34H28I4 The title of the article was Tetrahedral rigid core antenna chromophores bearing bay-substituted perylenediimides. And the article contained the following:
Two new representative methane- and adamantane-centered ‘antenna’ tetramers bearing bay-substituted 蟺-conjugated phenylethynyl-perylenediimides (PDICCPh) as chromophoric subunits, tetrakis-[1-(4-ethynylphenyl)-N,N’-bis(1-hexylheptyl)-perylene-3,4:9,10-tetracarboxylic diimide]-methane (1) and tetrakis-1,3,5,7-[1-(4-ethynylphenyl)-N,N’-bis(1-hexylheptyl)-perylene-3,4:9,10-tetracarboxylic diimide]-adamantane (2), were synthesized and their structural aspects were thoroughly studied by NMR spectroscopy. These PDI tetramers (1 and 2) represent the first successful example of incorporating the bay-substituted phenylethynyl-perylenediimides into the large rigid core tetrahedral frameworks. In these PDI tetramers, dynamic NMR experiments revealed the existence of perylene-centered conformational dynamic equilibrium (螖G鈮?15-17 kcal/mol), the primary cause of the observed spectral broadening in conventional 1H NMR spectra (295 K). In addition, PDI tetramers 1 and 2 were found to possess exceptional (photo)chem. stability, and their corresponding photophys. properties (蔚max鈭?80,000; 蟿FL=6.9 ns; 桅FL鈭?0%) make them viable candidates for various photonic applications and are in good agreement with other related multichromophoric PDI-based systems. The experimental process involved the reaction of 1,3,5,7-Tetrakis(4-iodophenyl)adamantane(cas: 144970-30-9).COA of Formula: C34H28I4
