3′, 3′-Dimethyl-6-nitrospiro(2H-1-benzopyran-2,2′-indoline) -1′-propionic acid [I] was modified with a methoxy group at 8th position of the pyran ring. The stability of photoresponsive activity was 3.4 times higher than that of [I]. The new spiropyran is promising for the photocontrol of enzyme activity.
