Synthesis, Crystal Structure and Nonlinear Optical Properties of a Novel Imidazole DerivatiVe
摘要
Abstract
A new compound 1-[trans-4-（（N-ethylcarbazolyl） vinyl） phenyl] imidazole（C25H22N3,Mr=364.46）has been synthesized, and its crystal structure was determined by single-crystal X-ray diffraction method. The crystal is of monoclinic, space group P21/c with a= 9.298（2） A,b=8.648（2） A,c=25.394（7） A,μ=110.46（3）°,V=1912.9（8） A3,Z=4,Do=1.266g/cm3 μ= 0.075mm-1,F（000）=772, The structure was refined to R=0.0685 and wR=0.1612 for 3570 unique reflections with Rirx=0.0645. The structural determination shows that the molecular structure is a perfectly planar π-conjugated system, and there is a high electronic delocalization in the molecule. The compound shows photoluminescence with a maximum emission at 439nm and a shoulder emission at 458nm upon the maximum-excitation wavelength at 264nm.关键词
