New thiophene-based poly(azomethine)s bearing tetraphenylsilane moieties along their backbone. Optical, electronic, thermal properties and theoretical calculations

A new series of conjugated thiophene-based poly(azomethine)s (PAZThAs) containing tetraphenylsilane (TPS) cores and thiophene or bithiophene moieties along the backbone were obtained from silicon-containing diamines and commercial 2,5-thiophenedicarboxaldehyde and 2,2′-bithiophene-5,5′-dicarboxaldeh
