Four thiocyanate-free ruthenium sensitizers (DUY24-DUY27) containing 2-thienylpyridine moiety as cyclometalating core were synthesized for dye-sensitized solar cell (DSC) application. To the best of our knowledge, DUY24-DUY27 are four best-efficiency sens

A new star-shaped donor-acceptor molecule has been synthesized for application as the donor material in solution-processed bulk-heterojunction organic solar cells (OSCs). The molecule consists of a triphenylamine (TPA) unit as the core and a donor unit with three arms containing benzo[1,2,5]thiadiazole (BT) acceptor units and 5,5″-dihexyl-2,2′:3′,2″- terthiophene (tTh) end groups. The molecule, denoted S(TPA-BT-tTh), exhibits a broad absorption band in the wavelength range 300-650 nm and high hole mobility of 1.1×10-4 cm2 V-1 s-1. An OSC device based on S(TPA-BT-tTh) as donor and [6,6]-phenyl C 71-butyric acid methyl ester (PC70BM) as the acceptor (1:3, w/w) exhibited a power conversion efficiency of 2.28% with a short circuit current density of 6.39 mA/cm2 under illumination of AM.1.5, 100 mW/cm2.

(Matrix Presented) Thiophene dendrons and dendrimers were designed and synthesized using a convergent approach. Metal-mediated coupling reactions were used in the synthesis. A rational approach allowed the formation of αα, ββ, and αβ linkages between the dendrons and thiophene units.

Supramolecular nano-composites 15T5N/ZnOx-PNH containing enhanced compatibilities of dendritic dye 15T5N and surface-modified nano-rod ZnOx-PNH were developed in this study. The physical properties of supramolecular nano-composites have been well investigated by theoretical calculation and various measurements, including UV–visible, PL, TEM, TCSPC, FT-IR, and CV. H-bonded nano-composite 15T5N/ZnO30-PNH possessed the saturated quenched fluorscence as dendritic dye 15T5N complexed with surface-modified nano-rod ZnO30-PNH. In contrast to nano-rod mixture 15T5N/ZnO (without surface-modification), more widened visible absorption band to promote more efficient photo-induced charge separation phenomenon was observed in supramolecular nano-composite 15T5N/ZnO30-PNH. Compared with surfactant T-PNH, less efficient electron transfer of surfactant T-PC6 was observed in TCSPC and PL measurements because of the steric hindrance of long alkyl chains (-C6H13) attached to surfactant T-PC6. Therefore, the triple H-bonds between dendritic dye 15T5N and surface-modified nano-rod ZnO30-PNH are verified to result in the desirable effective electron transfer in supramolecular nano-composite 15T5N/ZnO30-PNH.

, p. 819 - 822 (2011)
A novel large thiophene-fused polycyclic aromatics 1 based on pyrene 5 has been synthesized, and its structure was confirmed by 1H NMR, 13C NMR, MS, UV-vis and elemental analysis. The key steps of the synthesis involved the Stille cross-coupling reaction and followed by selective β-β oxidative cyclization of pendant thienyl rings by FeCl3 under mild conditions.
