摘要：

Photosublimation of the photoproduct of ethyl-4-formyl-1,3-dimethylpyrazole-5-carboxylate(EFDPC) has been observed for the first time at room temperature and normal atmospheric pressure. Steady state absorption spectroscopy and atomic force microscopic studies of EFDPC cast film as a function of UV/visible photoirradiation time revealed that upon photoirradiation EFDPC is converted to photoproduct first, which on further photoirradiation is evaporated from the substrate. This evaporation is a single photon phenomenon which is completely different from the laser ablation (sublimation) process.
