Abstract
본 연구에서는 2,2'-bispyrimidine (bpim), 2,2'-bipyridine (bpy), 5,5'-dimethyl-2,2'-bipyridine (5,5-mebpy), 5'-bromo-2,2'-bipyridine (5-brbpy), 5,5'-dibromo-2,2'-bipyridine (5,5-brbpy), 4,4'-dimethyl-2,2'-bipyridine (4,4-mebpy), 4, 4'- dihexyl-2, 2'- Bipyridine (4,4-hebpy), 1, 10'- Phenanthroline (phen), 3,4,7,8'- tetramethyl-1, 10'- Phenanthroline (3,4,7,8-phen)을 사용하여 단핵 Platinum착체를 합성하였다. 합성되어진 Platinum착체의 화학적 구조를 결정하기 위해서 1H(13C)-NMR, FT-IR을 사용하였으며, 광 물리학적 특성에 대한 측정은 UV-vis, PL을 통하여 측정하였다. 합성한 Platinum착체는 356 nm~421 nm영역에서 발광파장이 확인되었으며, DMSO용액에서 내부양자효율이 0.05~0.46으로 나타났다.
In this study, new platinum complexes were synthesized utilizing the ligand of a 2,2'-bispyrimidine (bpim), 2,2'-bipyridine (bpy), 5,5'-dimethyl-2,2'-bipyridine (5,5-mebpy), 5'-bromo-2,2'-bipyridine (5-brbpy), 5,5'-dibromo-2,2'-bipyridine (5,5-brbpy), 4,4'-dimethyl-2,2'-bipyridine (4,4-mebpy), 4,4'- dihexyl-2, 2'- Bipyridine (4,4-hebpy), 1,10'- Phenanthroline (phen), 3, 4, 7, 8'-tetramethyl-1, 10'- Phenanthroline (3,4,7,8-phen). In order to determine chemical structure of Synthesized platinum complexes, 1H(13C)-NMR, UV-vis and FT-IR were used and optical physics and chemical properties were measured PL. In the case of platinum complexes, wavelength has been identified 356~421 nm. Quantum efficiency in DMSO solution was appeared 0.05~0.46.
