Three positional isomers of thiophosphoranyl anthracene were synthesized and their photophysical properties investigated. By varying the position substituents, blue, green yellow solid-state fluorescence with differences in emission wavelength over 100 nm, assigned to intra- intermolecular effects, could be established.
