The phenylenevinylene-based two-photon absorbing chromophore (EA4BPA-VB) with a triphenyl amine as an electron donor was synthesized The two-photon absorption, (TPA) cross-section volvas of EA4BPA-VB measured by two-photon induced, fluorescence method with 80 fs-pulse laser ware found to be sigma(2) = 4.7 x 10(-48) cm(4)s/photon. By adding this chromophore into photo-reactive SCR resin, we have successfully fabricated 3-D micro-structure (a larva) with high spatial resolution at tow laser power with less than 5 mW To improve the resolution of 3-D patternings, we also investigated a voxel size and shape depending on laser exposure lime and concentration of TPA chromophore in SCR resin, at near-threshold exposure condition.
