Original Abstract

The syntheses, spectral measurements and the AM1 (Austin model 1) geometry optimisation of N,N0-bis-thiophen-2-ylmethylenehydrazine (IIIa), N,N0-bis-(3-methyl-thiophen-2-ylmethylene)-hydrazine (IIIb), N-[2,20]-bithiophen-5-ylmethylene-N0-thiophen-2-ylmethylene- hydrazine (IIIc), N,N0-bis-[2,20]-bithiophen-5-ylmethylene-hydrazine (IIId), N-[2,20; 50,200]-terthiophen-5-ylmethylene-N0-thiophene- 2-ylmethylene-hydrazine (IIIe), N-[2,20]-bithiophen-5-ylmethylene-N0-[2,20; 50,200]-terthiophen-5-ylmethylene-hydrazine (IIIf) and N,N0- bis-[2,20; 50,200]-terthiophen-5-ylmethylene-hydrazine (IIIg) are elaborated. The electron absorption spectra for all-trans conformers are obtained by ZINDO/S method and compared with the experimental data. The influence of the chain length on the electronic polarisability and second-order hyperpolarisability is investigated using the time-dependent Hartree–Fock method in AM1 approach
