Abstract
Described herein are luminescent sila- and germafluorenes. Also described herein are methods of making and using sila- and germafluorenes. The position and the type of substituent impact the absorption and emission properties in solution and in the solid-state and subsequently influence the role of sila- and germafluorenes as biosensors.
