摘要: The present invention provides crosslinked polymeric networks that are reversibly crosslinked upon exposure to light of a suitable wavelength. In one embodiment photocrosslinkable branched hydrophilic polymers containing photochromic groups are synthesized. Cinnamylidene groups and derivatives of cinnamylidene are preferably used as the photochromic agents or photocrosslinking agents.
