Chemical Stimuli Induced Phosphorescence Modulation of Secondary Thioamide-Based Pincer Platinum Complexes
摘要:
The photochemical properties of pincer platinum complexes bearing secondary thioamide groups have been examined. The presence of the coordinated secondary thioamide linkage in the pincer ligand was found to work as a reactive site upon addition of bases and anions and to result in modulating absorption and emission properties of the complexes.
Cationicpincerplatinum(II) complexes bearing secondarythioamide units showed aggregation-induced emission (AIE) activity in chloroform/hexane and methanol/water mixtures. Hydrogen bonding of the thioamide units and interionic interactions contributed to the AIE activities.
