In some embodiments, the present invention is directed to a method for chemically modifying 7-substituted coumarins to produce polymerizable monomers that are used to prepare photoresponsive materials. In one embodiment, 7-hydroxy-coumarin (umbelliferone) is so modified. The present invention also relates to the photoresponsive linear polymers, copolymers, and hybrid network materials produced from the polymerizable monomers, and the method for their preparation.
