Abstract
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 by1H NMR,13C 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.
