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.
Claims10
A method of measuring luminescence, the method comprising
- introducing a composition comprising
- a compound of Formula I,
- wherein R1 and R2 are each independently selected from the group consisting of hydrogen, alkyl, and aryl;
- and
- wherein R3, R4, R5, and R6 are each independently selected from the group consisting of hydrogen, alkoxy, Y, and
- with the proviso that at least two of R3, R4, R5, and R6 are selected from the group consisting of Y and
- wherein Y is selected from the group consisting of aryl, substituted aryl, heteroaryl, and substituted heteroaryl;
- a solvent;
- and
- a detergent;
- optically exciting the composition;
- and
- measuring luminescence produced by the compound of Formula I.
