| 摘 要： | 吲哚啉螺吡喃是一种重要的光致变色化合物,由于具有良好的变色回复性、抗疲劳性而得到广泛的关注.本文合成了1′-羟乙基-3′,3′-二甲基吲哚啉-6-硝基螺吡喃,研究了该化合物在紫外-可见光交替照射下紫外吸收强度的变化,并测试了光照前后化合物的荧光光谱.在开环态时,化合物具有优良的荧光性能,可以成功应用于细胞成像,在活细胞中可获得清晰的荧光成像图,同时也可以发挥螺吡喃光致变色可循环、耐疲劳等优势.

| Abstract: | Indolinospiropyran is a kind of photoresponsive compound,and it has attracted significant attention for its photoisomerization between two forms,excellent properties of fatigue counterac- tion.In this article,1'-(2-hydroxyethyl)-3',3'-dimethyl-6-nitriospiro (2H-1-benzopyran-2,2'-in- doline) was synthesized,and its absorption change by irradiation UV-vis as well as fluorescence spectral change was investigated.In ring-open form,because of its excellent fluorescence image in living cells,this compound can apply in bioimaging.Also,its properties of restorable and fatigue counteraction can be also well displayed. |
