First luminescent triphenyl silanol enabled by non-innocent acridine orange

The first organosilanol with blue-green light emitting property enabled by acridine orange through weak interaction is reported. Me. The isolation of photoluminescent triphenylsilanol induced by acridine orange is reported. The photophysical, and structural properties of triphenylsilanol-acridine orange salt are investigated. The reported silanol-amine salt is the first of its kind that portrays the blue-green emission. In solid-state, the triphenylsilanol molecule associates with acridine orange molecule through O-H center dot center dot center dot N hydrogen bond.
