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。
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 I was determined by x-ray diffraction method.I is monoclinic,space group P21 with 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 FL spectra shifted to the blue,and their fluorescence quantum yields got extremely lower than that of POEOP.
