compounds were structurally characterized and their properties were analyzed by spectroscopy, single crystal X-ray diffraction, electrochemistry and theoretical studies. Significant effect of substitutedpositions on photophysical properties were observed. The p -methylphenylthio group in 1- and 4-position significantly increases the absolute fluorescence quantum yield ( Ф F ) in solid state, decreases
