“…Further more, with the tolerance of radical polymerization to various functionalities, various TPA polymers bearing functional groups can be synthesized and further modified for different applications. The model of branched two-photon absorbing chromophore employed in this research is (E,E,E)-1,3,5-tristyrylbenzene (1) which has previously been synthesized and was found to exhibit excellent nonlinear optical properties [26][27][28]. To covalently attach the molecular structure of 1 to polymer backbone, a synthetic strategy is developed as depicted in Figure 1.…”

Abstract.A two-photon absorbing polymer has been prepared through radical copolymerization of methyl acrylate and a synthesized monomer containing a two-photon absorbing chromophore (E,E,E)-1,3,5-tristyrylbenzene (1), under conventional radical polymerization conditions. The synthesized polymer was characterized by nuclear magnetic resonance (NMR), infra-red spectroscopy (IR) and gel permeation chromatography (GPC). The linear and nonlinear optical properties were studied by measurement of UV-Vis absorption, fluorescent emission and two-photon cross-section. This synthetic strategy provided a facile approach for synthesis of photonic materials with adjustable chromophore concentration and high molecular weights.
