The synthesis, characterization, and photophysical properties of several novel silacyclopenadienes (siloles) will be presented. We present the preparation of 1,1-dimethyl-2,5-ditoluyl-3,4-diphenylsilacyclopenta-2,4-diene and 1,1-dimethyl-2,3,4,5-tetratoluylsilacyclopenta-2,4-diene. In an effort to increase the solubility of the parent tetraphenylsiloles in aqueous solvents, we have embarked on a synthetic strategy to replace phenyl substituents on the metallole core benzoate groups. A goal of the current research effort is to oxidize the benzylic carbons of the toluyl-substituted siloles to afford a more polar silole. The initial results of these transformations will be presented.
