title: Synthesis, characterization, luminescence, and non-linear optical properties of oxadiazole- and truxene-containing platinum(II) alkynyl complexes with donor-acceptor functionalities.
abstract: A series of luminescent platinum(II) alkynyl complexes containing 2,5-diphenyl-1,3,4-oxadiazole (oxa-2,5) and 10,15-dihydro-5H-diindeno[1,2-a;1',2'-c]fluorene (truxene) as the cores and different electron donors at the periphery has been synthesized and characterized. These complexes showed long-lived emissions in both solution and in the solid state at room temperature and have been found to exhibit two-photon absorption (2PA) and two-photon induced luminescence. Their 2PA cross-sections (sigma(2)) have also been determined.
