16.4.4 Photoswitchable Polymers

A naphthopyran-bridge-benzimidazole dyad,

which exhibits both ﬂuorescence and photochromism,

has been developed.

The structure is shown in Figure 16.5.

Irradiation with UV light induces the isomeriza-

tion of the naphthopyran component to the corre-

sponding merocyanine. The ﬂuorescence of the dyad

can be switched reversibly between ON and OFF

upon UV irradiation and thermal bleaching of
