The reaction of platinum 5,5"-(9,9-dioctyl-9H-fluorene-2,7-diyl)di-2,2'-bipyridine with 2,2'-bipyridine) PtCI2, (1,10-phenanthroline)PtC2 and (2,2'-bipyrimidine)PtC2: (2,2'-bipyridine)Pt[5,5"-(9,9-dioctyl-9H- fluorene-2,7-diyl)di-2,2'-bipyridine] (1) (2,2'-bipyrimi-dine)Pt[5,5"-(9,9-dioctyl-9H-fluorene-2,7-diyl)di- 2,2'-bipyridine] (2) (1,10-Phenantroline)-Pt[5,5"-(9,9-dioctyl-9H-fluorene-2,7-diyl)di-2,2'-bipyridine] (3). In the study, new platinum complex compounds were synthesized utilizing the ligand of a 5,5"-(9,9- dioctyl-9H-fluorene-2,7-diyl)di-2,2'-bipyridine). Each of the three complexes was obtained through the reaction carried out in this study. These complexes were analyzed using 1H(13C)-NMR, PL, and a UV-vis spectrophotometer. The maximum wavelengths of complexes 1, 2, and 3 appear at 519 nm, 375 nm, and 517 nm, respectively. The quantum yields of these complexes are in the range of 0.35-0.67.
