Abstract:

New poly(bis-3, 4-ethylenedioxythiophene methine)s derivatives with typical electro-optical moieties of thiophene, carbazole and fluorene as the side chains are obtained by facile solid state polymerization (SSP) or melt state polymerization (MSP). Detail characterizations of these polymers are carried out and some key monomers' crystals are obtained for structures analysis. It is found that existence of alkyl chains decrease monomers onset temperatures for SSP (Tonset) due to the weakening of the intermolecular interaction in crystals.

Key words: Poly (bis-3, 4-ethylenedioxythiophene methine) s derivatives, Solid and melt state polymerization, Alkyl chain effect
