Novel bis-tridentate Ir(III) complexes are of great interest in the development of blue-emitting organic light-emitting diodes (OLEDs) due to their rigid and robust mol. architecture. In this work, both the functional 6-pyrazolyl-2-phenoxypyridine (pzyPx) and 6-(1,2,4-triazolyl)-2-phenoxypyridine (tazPx) were used as chromophoric chelates in the construction of the blue-emitting Ir(III) phosphors. Accordingly, the substitution of pzyPx with tazPx chelates retains the desired characteristics, i.e. both high quantum yields (>92%) in solution and shortened radiative lifetime (τrad) (from 19.8 to 2.5 μs), resp. The theor. calculation reveals that the triazolate moiety contributes considerably to the radiative transition, to which the greater iridium involvement in T1 → S0 transition of tazPx-based complex is responsible for the shortened τrad. Consequently, enhanced photostabilities in degassed toluene and competitive performances with maximum EQE of 19.2% with CIE coordinates of (0.17, 0.22) were observed from the tazPx-based complex Px-33. In the part of experimental materials, we found many familiar compounds, such as 2,6-Dibromopyridine(cas: 626-05-1HPLC of Formula: 626-05-1)
2,6-Dibromopyridine(cas: 626-05-1) belongs to pyridine. Pyridine-based materials are valued for their optical and physical properties as well as their medical potential. Additionally, pyridine-based natural products continue to be discovered and studied for their properties and to understand their biosynthesis.HPLC of Formula: 626-05-1
