摘　　要：为制备出一种能在紫外光照条件下具有分子开关功能的化合物——一乙烯基噻吩螺噁嗪,将乙烯基通过双键引入了螺噁嗪。通过质谱与核磁氢谱对所合成的一乙烯基噻吩螺噁嗪化合物的结构进行了表征。利用紫外-可见吸收光谱对化合物紫外光照前后的吸收谱进行了对比发现,该化合物受紫外激发可由无色变为蓝色,在氯仿溶液中具有良好的光致变色性能,并对一乙烯基噻吩螺噁嗪进行荧光测试,结果显示,该化合物受392 nm的光照射后可在乙醇溶液中发射445 nm的荧光。利用一乙烯基噻吩螺噁嗪上述的光致变色性能和荧光性能设计出一种可实现非与非功能的分子逻辑门。We introduce vinyl into the spirooxazine by using double bonds and compound,and it yields the vinyl thiophene spirazine,a kind of compound which would have the function of molecular switch at the condition of ultraviolet light.By using mass spectrometry and nuclear magnetic hydrogen spectrum,we investigate the structure of the compound.Comparing the absorption spectrum,after the compound has been exposed to the UV-light,we found that the compound would be changed from colorless to blue,and has great photochromic property in chloroform solution.Verified by fluorescence measurements,it shows that the compound could emit fluorescence of 445 nm after being exposed to 392 nm light.According to the property mentioned before,we design a molecular logic gate.
