Long-lived photoinduced charges in donor-acceptor anthraquinone-substituted thiophene copolymers
Article Abstract:
The photoinduced charge-transfer properties of a series of polyalkylthiophene copolymers, carrying anthraquinone substituents covalently linked to the conjugated backbone, are analyzed in the solid state by photoinduced absorption (PA) and light-induced electron spin resonance (LESR) spectroscopy. The results have showed that in these polymers, the number of acceptor substituents in the chain, easily tuned by chemical tailoring, plays a vital role in the photoexcitation scenario.

Vibrational spectroscopy of pDTT3-a low band gap polymer based on dithienothiophene
Article Abstract:
The electrochemical redox processes of poly(dithieno[3,4-b:2E,2E-d]thiophene)(pDTT3) are reported based on the attenuated total reflection Fourier transform infrared studies. Vibrational spectroscopic studies are carried for this low band gap conjugated polymer with a polythiophene-like backbone, where an aromatic moiety is fused to each thiophene ring, in situ during electrochemical oxidation and reduction.
