摘要： 由氯代丁烯二酰氯和α-氨基苯乙酮的盐酸盐经缩合、关环反应合成了标题化合物Ⅰ、Ⅱ。用元素分析、紫外光谱、红外光谱、质谱鉴定了其结构,并用X射线衍射法测定了Ⅰ的晶体结构,其空间群为P21,晶胞参数α=0.8450(2)nm,b=0.6994(1)nm,c=1.5432(5)nm,β=102.38(2)°,Z=2.由于在烯键碳原子上引入体积较大的氯原子,使Ⅰ和Ⅱ分子的平面性变差,其电子光谱相对于反式-1,2-双[2-5-苯基唑基)]乙烯(POEOP)有蓝移,且荧光量子产率明显下降。

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,Dx=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.
