Branched oligothiophene silanes with the efficient nonradiative energy transfer between the fragments
Borshchev,Ponomarenko,Kleymyuk,Luponosov,Surin,Muzafarov
, p. 797 - 805 (2010)
The synthesis of new dendrimers and branched oligothiophene silanes containing bithiophene groups at the periphery and quaterthiophene fragments at the center of the molecule is described. Specific features of bithiophene silane bromination were shown, and the conditions for the efficient synthesis of methyltris(5-bromo-2,2′-bithiophen-5-yl)silane have been found for the first time. The optical properties of the synthesized compounds were studied. The efficiency of the electron excitation energy transfer between the fragments of branched bi-and quaterthiophene silanes was measured.
Reducing Energy Disorder of Hole Transport Layer by Charge Transfer Complex for High Performance p–i–n Perovskite Solar Cells
Xu, Guiying,Xue, Rongming,Stuard, Samuel J.,Ade, Harald,Zhang, Chenjie,Yao, Jianlin,Li, Yaowen,Li, Yongfang
, (2021)
Solution-processed organic semiconductor charge-transport layers (OS-CTLs) with high mobility, low trap density, and energy level alignment have dominated the important progress in p–i–n planar perovskite solar cells (pero-SCs). Unfortunately, their inevi

Heptafluoropropylation of Various Substituted Thiophenes with Bis(heptafluorobutyryl) Peroxide. Preparation of 3-Heptafluoropropylthiophen
Yoshida, Masato,Yoshida, Tatsuro,Kamigata, Nobumasa,Kobayashi, Michio
, p. 3549 - 3552 (1988)
The heptafluoropropylations of several substituted thiophenes with bis(heptafluorobutyryl) peroxide were studied.The orientations of the heptafluoropropylation were examined and compared with those of usual electrophilic substitution.The method for the preparation of 3-heptafluoropropylthiophene was also explored.
BN-Substituted coronene diimide donor-acceptor-donor triads: photophysical, (spectro)-electrochemical studies and Lewis behavior

Boron/nitrogen substituted polyaromatic hydrocarbons (PAHs) are unique materials, with similar molecular structures to their carbon/carbon analogs, but different electronic properties. We report how these may be tuned by substitution at the B and/or N ato
Catalytic B-C Coupling by Si/B Exchange: A Versatile Route to π-Conjugated Organoborane Molecules, Oligomers, and Polymers

Conjugated organoboranes have emerged as attractive hybrid materials for optoelectronic applications. Herein, a highly efficient, environmentally benign catalytic B-C bond formation method is presented that uses organosilicon compounds, dibromoboranes, and the metal-free organocatalyst Me3SiNTf2. This Si/B exchange approach has been successfully applied to the synthesis of arylborane molecules 4a-c, oligomers 8a,b, and polymers 8a′,b′. Photophysical investigations, supported by TD-DFT calculations, reveal highly effective π-conjugation in thienyl- and furylborane species; the latter are also highly emissive.
