Platinum substituted boroles

Abstract

The unprecedented 1-metalloborole [(Cy(3)P)(2)Pt(Cl)(BC(4)Ph(4))] (1) and its T-shaped cationic derivative (2) were successfully prepared and structurally characterized. Fine-tuning the electronics of the boron-bound metal complex leads to a significant change in the lowest electronic transition energy of the 1-metalloboroles.
