| 1 | 2026 Thesis | Synthesis and photophysical properties of blue phosphorescent iridium (III) complexes with alkoxy functionalised ligands for potential oled applications Nur Khaliesa Zulkarnaen This research aims to synthesise and characterise new blue phosphorescent iridium(III) complexes and analyse their photophysical properties. Three iridium(III) complexes were synthesised: bis(2-(2-butoxy-4-fluorophenyl)pyridine)(2,6 difluorobenzyltriazolpyridine)iridium(III) ion (C1), bis(2-(2-ethoxy-4- fluorophenyl)pyridine)(2,6-difluorobenzyltriazolpyridine)iridium(III) ion (C2) and bis(2-(2-butoxy-4-fluorophenyl)pyridine)(imidazolpyridine)iridium(III) ion (C3). Complexes of C1 and C2 were obtained via reaction of dichloro-bridged iridium(III) dimers with N-heterocyclic carbene ligands, while C3 was prepared using the same dimer reacted with 2-(1H-imidazol-2-yl)pyridine. All complexes were characterised using spectroscopic techniques: _H, __C and distortionless enhancement by polarisation transfer 135 (DEPT-135) nuclear magnetic resonance (NMR), Fourier transform infrared (FTIR) and liquid chromatography-mass spectrometry using electrospray ionisation (LC-ESI/MS).
