چکیده انگلیسی
A new type of copolymer of alkylated oligomeric thiophene and polyethylene oxide (PEO) was synthesized. Synthesis was performed by the condensation reaction of alkylated dimethylester of oligothiophene dicarboxylic acid with PEO. The synthesized six-membered oligothiophene was prepared by directed synthesis of cyclization of the thiophene ring with strictly defined position of alkyls, settled on the outer thiophenic rings. The copolymer is soluble in common organic solvents and in the solid state, which creates structurally-organized clusters composed of conducting (oligothiophenic) and non-conducting (PEO) segments. Separated thiophenic phase was confirmed by TEM, and localized fluorescence of thiophenic clusters.
