Synthesis, structure and nonlinear optical properties of two novel two-photon absorption chromophores

Abstract

Two triphenylamine-based derivatives that can be used as two-photon absorption chromophore, tris{4-[4-(3-trifluoromethyl-3-oxopanoyl)]phenyl}amine (1) and tris{4-[4-(3-phenyl-3-oxopanoyl)] phenyl} amine (2) were successfully synthesized and fully characterized by elemental analysis, IR, 1 H NMR and MS. The single crystal X-ray diffraction analysis showed that the molecules possess D-(π-A) 3 structures. One-and two-photon absorption and fluorescence in various solvents were experimentally investigated.A data recording experiment proved the potential application of these chromophores.two-photon absorption, triphenylamine derivative, chromophore, crystal structure

Multi-carbazole derivatives for two-photon absorption data storage: Synthesis, optical properties and theoretical calculation

“…Furthermore, we attempt to use new multi-carbazole derivatives as optical data storage materials by the method of void creation in polymer (Poly(methylmethacrylate)) as the references [29][30][31]. The optical system that we used for data recording and reading with the new material was similar to the instrumental setup used in the literature [32][33][34]. The novel TPA materials possess potential application perspectives due to their simple preparation and efficient initiating properties.…”
