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.

Key words: indolinospiropyran, restore by UV-vis, fluorescence, bioimaging
