英文摘要	Two novel benzylidene cyclopentanone dyes (1 and 2) containing coumarin moiety were synthesized. their photophysical properties were investigated using uv-vis spectra, fluorescence spectra and two-photon excited spectra. the maximum two-photon absorption cross-sections (delta(max)) of two compounds were determined as 939 gm and 1150 gm, respectively, with femtosecond laser pulses. combined with commercial photoinitiator 4,4'-dimethyl-diphenyliodinium hexafluorophosphate (omnicat 820), both of two dyes exhibited higher sensitizing photopolymerization efficiency than the common used high-efficient photosensitizer 2,5-bis-[4-(dimethylamino)-benzylidene]-cyclopentanone in one-photon photopolymerization experiments. using 2 as sensitizer or initiator directly, 2d and 3d nanopatterns were successfully fabricated by two-photon initiated polymerization.
