The synthesis of N-heterocyclic carbene precursors and their cyclometalated platinum(II) carbene complexes based on hexahydroimidazo[1,5-a]pyridine are reported in this study. The properties of these platinum complexes were characterized by various techniques, and their photophysical and electrochemical behaviors were investigated. Quantum chemical calculations were used to rationalize the experimental results.
The synthesis of N-heterocyclic carbene precursors based on the hexahydroimidazo[1,5-a]pyridine and their corresponding cyclometalated platinum(II) carbene complexes is reported. All compounds are fully characterized by standard techniques and additionally X-ray structures could be obtained for three complexes. The photophysical properties of these platinum complexes were investigated by absorption and photoluminescence measurements. All complexes showed strong phosphorescence at room temperature in the sky-blue area with quantum yields of up to 71 %. Additionally, their electrochemical properties were examined by voltammetry experiments. All results were rationalized by quantum chemical DFT calculations (PBE0/6-311G*).
