Platinum tetrakis(2,4,6-triethylphenyl)porphyrin (Pt-1) was synthesized and its structural (X-ray), electrochemical and photophysical properties were fully characterized. Comparative studies of Pt-1 and its unsubstituted analog PtTPP show the effect of sterically congesting ortho-substituents on the dynamics of the triplet excited states. Lowered quenching rates by 3-4 times were observed for Pt-1vs. PtTPP in the presence of oxygen and perylene, and in concentration (self)-quenching experiments.

C3-Symmetric, tripodal catalyst 4 based on 1,3,5- triethylbenzene, which incorporates the features of a molecular receptor, is shown to catalyze Michael addition reactions ofcarbonyl compounds to β-nitrostyrenes in a high stereoselectivity (up to 99:1a dr and up to 98%ee). Copyright
