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 H-1 NMR, C-13 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.
