Abstract

A thiophene derivative, which has a chemical structure of formula (1): wherein, X is a substituted or non-substituted C 6 -C 20 aromatic or C 1 -C 20 aliphatic group; R 1 and R 2 are independently H, a C 1 -C 10 linear, branched, or cyclic aliphatic group, or connected with the carbon atoms of formula (1) to form a first heterocyclic ring; R 3 and R 4 are independently H, a C 1 -C 10 linear, branched, or cyclic aliphatic group, or connected with the carbon atoms of formula (1) to form a second heterocyclic ring; and b is an integer ranging from 1 to 10, with a proviso that X is not when all of R 1 , R 2 , R 3 and R 4 are H.
