Novel Coumarin/Benzylidene Cyclopentanone Dyes for Two-Photon Polymerization
For exploring high-efficient two-photon polymerization (TPP) materials, two novle benzylidene cyclopentanone dyes containing coumarin moiety were synthesized. These two dyes share the same formula and possess similar structures, except for different bridging positions between the benzylidene cyclopentanone and coumarin moieties. Through investigating their linear and nonlinear photophysical and photochemical properties, combined with theoretical calculations of their ground state and excited state properties, the significant effect of the bridging position on the electronic structure, photophysical and photochemical properties of the dyes was found. Furthermore, highresolution 2D and 3D nano-patterns containing low amounts of small molecule residue were successfully fabricated by TPP, demonstrating the extensive application prospects of these dyes in the fabrication of micromachines, microsensor arrays and biomedical devices.
