Fitilis, I. published the artcileTwo-photon polymerization of a diacrylate using fluorene photoinitiators-sensitizers, Synthetic Route of 2909-77-5, the publication is Journal of Photochemistry and Photobiology, A: Chemistry (2010), 215(1), 25-30, database is CAplus.
Two-photon polymerization (TPP) of a diacrylate (monomer) using 2 different fluorene mols. as photoinitiators-sensitizers is reported. The fluorene mols. contain e– donating (triphenylamine) or e– withdrawing (phthalimide) edge substituents. An amine co-initiator is also used lowering the polymerization threshold. The dependence of the polymerization properties (threshold, polymerization rate, lateral and axial resolution) on the type of resin, the writing power and speed as well as on the NA of the focusing lens is studied. The fluorene with triphenylamine substituent exhibits favorable properties as TPP photoinitiator-sensitizer compared to the fluorene with phthalimide, although its 2-photon absorption cross-section is smaller. Polymerization of the pure monomer or monomer-amine composite (i.e. without fluorene) is also reported.
