title: A Study of Phosphorescent Light Emitting Using Cyclometalated Pt(II) Complexes.
abstract: The reaction of platinum [Pt(4-(N,N-bis(piridyl)amino)stilbene)]Cl2 with 5,5"-(9,9-dioctyl-9H-fluorene- 2,7-diyl)di-2,2'-bipyridine, 2,2'-bipyridine, and 1,10-phenathroline affords the following complexes: [(4-(N,N-bis(piridyl)amino)stilbene)Pt(5,5"-(9,9-dioctyl-9H-fluorene-2,7-diyl)di-2,2'-bipyridine)] (1), [(4-(N,N-bis(piridyl)amino)stilbene)Pt(2,2'-bipyridine)] (2), and [(4-(N,N-bis(piridyl)amino)stilbene) Pt(1,10-phenathroline)] (3). In this study, new platinum complex compounds were synthesized utilizing the ligand of a 4-(N,N-bis(piridyl)amino)stilbene system. These complexes were analyzed using a 1H(13C)-NMR, UV-vis and PL spectrophotometer. The maximum wavelengths of complexes 1, 2, and 3 appear at 409 nm, 410 nm, and 503 nm, respectively. The quantum yields of these complexes are 0.32-0.92.
