摘要:
Two new arylalkyne ligands L1 (D-pi-D' type) and L2 (D-pi-A type), and their coordinated Platinum(II) diimine diacetylides 1 (D-pi-D'-pi-[Pt]-pi-D'-pi-D type) and 2 (D-pi-A-pi-[Pt]-pi-A-pi-D type) were designed and synthesized (where D represents electron donating group and A represents electron accepting group). Photophysical properties measurements indicated that 2 displayed orange-red fluorescence with relatively high fluorescence quantum yield and strong two-photon absorption (2PA) cross-section. The influence of metal on the electronic structure and property was investigated by theoretical calculations and cyclic voltammograms. (C) 2011 Elsevier B. V. All rights reserved.
