Two silanediol derivatives bearing 9-anthryl (2) and 1-pyrenyl (3) groups have been developed for fluorescence detection of anions. Receptor 3 showed favorable ratiometric response by fluorescence spectroscopy upon the addition of biologically relevant anions, such as acetate and dihydrogen phosphate in acetonitrile.

Di(1-pyrenyl)silane and methane derivatives showed unprecedented intramolecular excimer emission in polar organic solvents such as DMSO and the ratio of excimer/monomer emissions strongly depends on the dielectric constants of the solvents.
