SYNTHESIS, CHARACTERIZATION OF A NOVEL CONJUGATED STRUCTURAL OLIGOMER

摘要

An octupolar star-shaped ladder-type oligomer composed of electron deriving from 1,3,5-triazine core end-capped by either an electron donating carbazolemoiety (TA(TL)-Ph(3)-CBZ) have been designed and synthesized to investigate the structure-properties relationship of highly efficient multiphoton absorbing materials. The newly synthesized molecules were characterized by 1H NMR, 13C NMR and mass spectrometry. Linear optical properties of the oligomer were investigated by UV-vis and fluorescence spectrometries, as well as the nonlinear optical properties were characterized by two-photon excited fluorescence (2PEF) measurement.
