4 - boronobenzoic acid reacts with 2 - iodo - 4, 6 - dimethylpyrimidine and then 2 -boronobenzoic-4,6-bis(4-N,N-ethylaminostyryl) pyrimidine (L) was efficiently synthesized by improved Ullmann reaction. The structure was characterized by 1 H NMR, 13 C NMR, IR and MS spectra. The optical properties of L were systematically studied using UV - vis absorption, fluorescence spectra. The spectral properties were explained based on TD-DFT calculations. The results indicated that L exhibited good optical properties and large two -photon absorption cross-section.
