We report a controlled chain-growth polymerization of methyl 3-octylaminobenzoate having a bithiophene chromophore at the 5-position of the benzene ring with the improved polymerization activity, which gives poly(N-octyl-m-benzamide)s with the better solubility. The introduction of a terthiophene chromophore at the propagating end is also described. From spectroscopic data and theoretical investigations, it was found that neighboring bithiophene chromophores have the π–π interaction and the excited energy can migrate along the polymer chain.
