Five novel cationic cyclometalated Ir(III) complexes of type [(C?C)IrX(PPh3)2(dmbpy)]A (X = halogen; dmbpy = 4,4?-dimethoxy-2,2?-bipyridine; A = counterion) were synthesised and characterised. Complexes 1?3 ([(C?C)IrCl(PPh3)2(dmbpy)]A) have different anions (A = Cl?, CF3SO3 ?, PF6 ?) and complexes 4?5 ([(C?C)IrX(PPh3)2(dmbpy)]PF6) have different halogen ligands (X = Br?, I?). Changing either the counter anion or halogen ligand altered the photophysical properties of the complexes. Interestingly, complex 1 (X = Cl, A = Cl?) did not exhibit mechanochromism, while the other four complexes all displayed mechanochromic properties. Crystal structures were determined for all compounds, and two types of single crystals are obtained for compounds 4 and 5. All complexes displayed bright solid-state phosphorescence, and reversible room-temperature mechanochromic luminescence was observed for complexes 2?5. The mechanism of the mechanochromic behaviour was investigated by combining powder and single-crystal X-ray diffraction analyses.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. Reference of 2926-30-9, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 2926-30-9, in my other articles.
