| Abstract: | Two carbazole-based polymerization initiators possessing blue fluorescence emission have been synthesized via Wittig reaction
in the solid phase at room temperature. Two-photon excited fluorescence (TPEF) spectra for them were investigated under 800
nm fs laser pulse and two-photon absorption cross sections were determined by the Z-scan technique. Then two-photon initiating
polymerization (TPIP) microfabrication experiments were successfully carried out. Three-dimensional lattice and artificial
defects were gained, indicating that they were viable candidates for the two-photon polymerization initiator in practical
application of microfabrication.
