Abstract

Abstract: Two new compounds trans-1,2-bis[2-(5-phenyloxazolyl)]dichloroethene(I) and trans-1,2-bis[2-(5-phenyloxazolyl)]chloroethene(Ⅱ) were synthesized.They were identified by elementary analysis,UV,mand MS.The crystal structure of Iwas determined by x-ray diffraction method.Iis monoclinic,space group P2₁with a = 0.8450(2)nm,b=0.6994(1)nm,c=1.5432(5)nm,β=102.38(2)°,V=0.8907 nm³,D_x=1.429g/cm³,μ=3.79 cm^-1,F(000)=392,Z=2.Because of large chlorine atom attached to double-bond carbon atom,the planarity of Ⅰand Ⅲ became poor. Their UV and FLspectra shifted to the blue,and their fluorescence quantum yields got extremely lower than that of POEOP.
