Photochromic symmetrical diarylethene derivatives 1a-6a bearing different long alkyl chains at 2-position of thiophene rings have been synthesized and their structures have been determined by single-crystal X-ray diffraction analysis. The effect of alkyl chain length on their optoelectronic properties, such as photochromism in solution as well as in the crystalline phase and electrochemical performance was investigated in detail. These diarylethenes have showed good photochromic behavior both in solution and in the single crystalline phase. Introduction of the long alkyl chains at 2-position of bis(5-formyl-3-thienyl)perfluorocyclopentene increased the absorption coefficients of both open- and closed-ring isomers and induced bathochromic shifts of the maximal wavelength absorption of the closed-ring isomers. The long alkyl chains can also decrease the cyclization/cycloreversion quantum yields and the oxidation potentials. The cyclic voltammetry indicated that the band gap of these diarylethene derivatives was significantly affected by the alkyl chain length.

It's all about polymers: All-polymer solar cells (all-PSCs) based on six perylene diimide containing polymers (PX-PDIs) as acceptor materials and two polythiophene derivatives (P3HT and PT1) as donor materials were investigated systematically (see picture). The highest power-conversion efficiency (PCE) of all-PSCs was 2.23 %, one of the highest PCEs of polymer/polymer blend photovoltaic devices reported to date. Copyright
Effect of conjugated side groups on the photovoltaic performances of triphenylamine-based dyes sensitized solar cells
Long, Jun,Liu, Xunshan,Guo, Huan,Zhao, Bin,Tan, Songting
, p. 222 - 231 (2016)
Three novel organic dyes (LD1, LD2 and LD3) with conjugated side groups on the thiophene π-bridge are designed and synthesized for dye sensitized solar cells (DSSCs). The photophysical, electrochemical, and photovoltaic properties of the dyes have been successfully tuned by incorporating different conjugated side groups into the thiophene π-bridges moieties of dyes. Compared with the analogous dyes with non-conjugated side groups, the side group-conjugated dyes exhibited wider absorption spectra, higher molar extinction coefficients, and better photovoltaic performances. For the LD2-based DSSCs, the maximum power conversion efficiency (PCE) of 7.71% is obtained under AM 1.5 G irradiation (100 mW cm-2). The result demonstrates that high-performance DSSCs can be acquired by choosing suitable conjugated side groups into the π-bridges moieties of organic dyes.
6-(Arylvinylene)-3-pyridinylboronic esters. Part 1: Versatile building blocks for conjugated chromophores via Suzuki cross-coupling
Leclerc, Nicolas,Serieys, Isabelle,Attias, André-Jean
, p. 5879 - 5882 (2003)
This paper describes a general approach for the synthesis of conjugated 6,6′-disubstituted-3,3′-bipyridine chromophores. As preliminary results, 6-(4-hexyl-2-thienylvinylene)-5-methyl-3-bromopyridine, 6-(4-ethanol-2-thienylvinylene)-5-methyl-3-bromopyridine, and the corresponding 3-pyridinylboronic esters have been prepared. Coupled by Suzuki reaction, they gave the conjugated chromophores (I) and (II) in high yields and multigram scales.
