摘要：
A novel eight-branched poly(ethylene glycol), PEG, macromer having a nitrocinnamate moiety as a pendant group was synthesized and found to form a photoscissile hydrogel upon exposure to 365 nm radiation in the absence of photoinitiators or catalysts. The processes of photocrosslinking and photocleavage were clearly characterized by environmental scanning electron microscopy (ESEM).
