two backbone diarylethene polymers were synthesized through convenient routes. The solubility
photochromism and fatigue resistant property were studied. The two obtained polymers showed the reversible photochromic ability and excellent fatigue resistance. In the synthesis process of the two polymers
diarylethene and copolymer units were connected using rigid and flexible connections
respectively
and thus obtained diarylethene polymers with different spectral properties and molecular weight.
