Abstract
Four new two-photon polymerization initiators have successfully synthesized with D–π–A–π–D type structure in which the carbazole or phenothiazine moiety acts as a donor, phenylacetylenyl as a conjugate linker and the Fluorenone or thioxanthone as an acceptor. These four compounds exhibited low fluorescence quantum yields (Φ) of FT-CAA-C6 (1.65%), FT-PTAA-C6 (0.01%), TX-CAA-C6 (3.56%) and TX-PTAA-C6 (0.02%) in dichloromethane. And, the δTPA values of FT-PTAA-C6 reached a maximum value of 527 GM. In addition, three-dimensional woodpile microstructure was fabricated via two-photon polymerization using FT-CAA-C6 as an initiator which possessed potential applications due to simple preparation.
