Patent ID: 8313978

Claim:
A method of preparing a poly(oligothiophene-arylene) derivative, the method comprising: adding a catalyst selected from the group consisting of Pd complexes and Ni complexes to a monomer solution, the monomer solution including a first monomer of formula 1 and a second monomer of formula 2; and preparing the poly(oligothiophene-arylene) derivative by a polycondensation reaction, wherein formula 1 is wherein A 1 is a halogen atom, a trialkyltin group or a borane group, A 2 is a halogen atom, a trialkyltin group or a borane group, R 1 is a hydrogen atom, a C 1-20 linear, branched, or cyclic alkyl group, a C 1-20 alkoxyalkyl group or a C 1-16 linear, branched, or cyclic alkoxy group, and a is an integer from 1 to 10, and wherein formula 2 is wherein A 3 is a halogen atom or a trialkyltin group, A 4 is a halogen atom or a trialkyltin group, Ar 1 is C 2-30 heteroaromatic structure comprising at least one electron-withdrawing imine nitrogen atom in the heteroaromatic structure or a thiophene-arylene comprising the C 2-30 heteroaromatic structure, and b is an integer from 1 to 4.
