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⋯N hydrogen bond. © 2018 Elsevier B.V.
