The chiral iridium rotors Ir(ppy)2(pyX)Cl (X = C≡C-SiR3, R = alkyl) remarkably contain two distinct rotational conformers in the ground (S0) and excited (T1) states that can be detected by NMR and emission measurements respectively at variable temperatures. The observed phosphorescent emissions, vibronic (involving L = ppy) and broad (L = pyX), arise from different triplet ligand to metal charge transfers from the two rotational conformers at distinct ³MLCT excited states. Both conformers exist in these Ir(ppy)2(pyX)Cl rotors due to the electron-withdrawing, conjugated substituent X. [ABSTRACT FROM AUTHOR] |
