, p. o91-o92 (2003)
The molecules of the title compound, C12H6N2S4, lie on centres of symmetry. The thiophene and thiazole rings are almost planar and their planes make a dihedral angle of 1.68 (8)°. In the crystal structure, there is a relatively short intermolecular S...S contact distance of 3.5786 (9) A.

Two novel thiazolo[5,4-d]thiazole containing donor-acceptor type alternating copolymers, poly[2-(5-(2-decyl-2H-benzo[d][1,2,3]triazol-4-yl) thiophen-2-yl)-5-(thiophen-2-yl)thiazolo[5,4-d]thiazole] (BTzTh) and poly[2-(5-(2-decyl-2H-benzo[d][1,2,3]triazol-4-yl)furan-2-yl)-5-(furan-2-yl) thiazolo[5,4-d]thiazole] (BTzFr) were synthesized by Stille coupling polymerization and their electrochemical and electrochromic properties were explored. Electrochemical activities of the spray-casted polymer films were determined by cyclic voltammetry. To evaluate the effect of thiophene and furan moieties on the optical properties of the copolymers, spectroelectrochemistry studies were performed. To examine the switching abilities, copolymer films were subjected to a double potential step chronoamperometry in their local maximum absorptions. Both thiazolothiazole-containing copolymers showed multichromic properties with low band-gap values 1.7 and 1.9 eV for BTzTh and BTzFr, respectively. The decent electrochromical properties together with solution processability make them important candidates for electrochromic applications. Copyright

We have synthesized four types of cyclopentadithiophene (CDT)based low-bandgap copolymers, poly[{4,4-bis(2-ethylhexyl)-4H-cyclopenta[2,1 -b :3,4-b']dithiophene-2,6-diy1}-alt(2,2'-bithiazole-5,5'-diy1)] (PehCDTBT), poly[(4,4-dioctyl-4H-cyclopenta[2,1-b:3,4-b']dithiophene-2,6-diyl)-alt(2, 2'-bithiazole-5,5'-diyl)] (PocCDTBT), poly[{4,4-bis(2-ethylhexyl)-4H- cyclopenta[2,1-b:3,4-b)']dithiophene-2,6diyl}-alt-{2,5-di(thiophen-2-y1) thiazolo[5,4-d]thiazole-5,5'-diy1}] (PehCDTTZ), and poly[(4,4-dioctyl-4H- cyclopenta[2,1-b:3,4-b']dithiophene-2,6diyl)-alt-{2,5-di(thiophen-2-y1) thiazolo[5,4-d]thiazole-5,5'-diy1}] (PocCDTTZ), for use in photovoltaic applications. The intramolecular charge-transfer interaction between the electronsufficient CDT unit and electron-deficient bithiazole (BT) or thiazolothiazole (TZ) units in the polymeric backbone induced a low bandgap and broad absorption that covered 300 nm to 700800 nm. The optical bandgap was measured to be around 1.9 eV for PehCDT-BT and PocCDT-BT, and around 1.8 eV for PehCDT-TZ and PocCDT-TZ. Gel permeation chromatography showed that number-average molecular weights ranged from 8000 to 14000 g mol-1. Field-effect mobility measurements showed hole mobility of 10 6-10-4 Cm2V-1 s-1 for the copolymers. The film morphology of the bulk heteroj unction mixtures with [6,6]phenyl-C61-butyric acid methyl ester (PCBM) was also examined by atomic force microscopy before and after heat treatment. When the polymers were blended with PCBM, PehCDT-TZ exhibited the best performance with an open circuit voltage of 0.69 V, short-circuit current of 7.14 mA cm-2, and power conversion efficiency of 2.23% under air mass (AM) 1.5 global (1.5 G) illumination conditions (100 mWcm-2).

A thiazolothiazole derivative is represented by the following Formula (I). In Formula (I), each R1 independently represents a straight chain alkyl group having 3 to 20 carbon atoms, a straight chain alkoxy group having 3 to 20 carbon atoms, a branched alkyl group having 3 to 20 carbon atoms, or a branched alkoxy group having 3 to 20 carbon atoms; and each R2 independently represents a hydrogen atom, a straight chain alkyl group having 1 to 20 carbon atoms, a straight chain alkoxy group having 1 to 20 carbon atoms, a branched alkyl group having 3 to 20 carbon atoms, or a branched alkoxy group having 3 to 20 carbon atoms.
