Abstract: A new two-photon photopolymerization initiator {4-[2-(4-bromophenyl)vinyl]phenyl}-diphenyl-amine(BVPDA) was synthesized and characterized by 1H NMR, 13C NMR and elemental analyses. The crystal structure was characterized by X-ray diffraction structural analyses. BVPDA belongs to the triclinic space group P1 with a=1.083 4(3) nm, b=1.562 5(2) nm, c=1.964 0(2) nm, α=92.807(8)°, β=103.647(10)°, γ=106.676(13)°, V=3.070 5(10) nm3, Z=6, T=293(2) K, Dc=1.383 g/cm3, R1=0.073 5 and wR=0.106 3. The linear absorption, one-photon fluorescence, one-photon fluorescence lifetime and two-photon fluorescence are experimentally studied. When pumped with 760 nm laser irradiation, BVPDA indicates a strong two-photon induced fluorescence of 462 nm. A microstructure using BVPDA as the initiator was fabricated using BVPDA as the initiator under irradiation of 200 fs, 76 MHz Ti:sapphire femtosecond laser at 760 nm.
