The synthesis and luminescent properties of a new, solution-processable conjugated polymer (P2) which was end-capped by anthracene were reported. The absorption, emission and electroluminescence (EL) spectra have been investigated respectively. The results indicated that the end-capped group of anthracene can obviously influence the energy band gap of the corresponding polymer (P1). The results were further confirmed by spectroscopic comparison with the model compounds. EL in the red region of the spectrum with a maximum at 600 nm was observed from the polymer film sandwiched between indium-tin-oxide and Al electrodes.
