Synthesis, Crystal Structure and Two-photon Absorption Properties of 4'-(N,N-di(4-hydroxymethyl phenyl) amino)phenyl-2,2': 6',2"-terpyridine
摘要:
A novel donor-acceptor (D-A) triphenylamino terpyridine derivative Lwas facilely synthesized and fully characterized, and its single crystals were obtained and determined by X-ray diffraction analysis. It crystallizes in triclinic, space group P1 with a=11.760(5), b=12.516(5), c=12.850(5)Å, α=67.141(5), β=65.284(5), γ=75.876(5)°, Mr=621.54, V=1575.6(11)Å3, Z=2, Dc=1.310 g/cm3, μ=0.245 mm-1, F(000)=648, the final R=0.0671 and wR=0.1869 for 11328 observed reflections with I>2σ(I). Linear and nonlinear optical properties of terpyridine derivative Lwere systematically investigated. The maximum two-photon cross-section of Lwas 382.5 GM (Goeppert-Mayer), measured by two-photon excited fluorescence (TPEF) method. This result demonstrates that the increase of intramolecular charge transfer (ICT) leads to enhanced two-photon absorption (2PA), which could be achieved by introducing additional electron-donor groups to the molecular framework.
