Abstract
Abstract The synthesis and characterization of poly(ethylene oxide)-b-poly(4-butyltriphenylamine)-b-(polyethylene oxide) triblock copolymers (PEO-b-PBTPA-b-PEO) with different block ratio are described. The optical properties of block copolymers were investigated by UV–vis absorption, and photoluminescence (PL) spectroscopy. From atomic force microscopy (AFM) observation of the annealed thin films of block copolymers, microphase-separated morphology was observed.
