This paper presents the results of absorption spectra, fluorescence properties and the effect of solvents on UV-Vis spectra of dye quaternized 4-acetylamino-N-2-aminomethylpyridine-1,8-naphthalimide. The fluorescency of the dye was evaluated and its Stokes shift value was 6140 cm-1 in DMF. The solvatochromism behavior of the novel compound is investigated by studying its spectra in pure organic...

A family of extended 5-modified-6-aza-uridines was obtained via Suzuki coupling reactions with a common brominated precursor. Extending the conjugated-6-aza-uridines with substituted aryl rings increases the push-pull interactions yielding enhanced bathochromic shifts and solvatochromism compared to the parent nucleosides. For example, the methoxy substituted derivative 1d displays λmax abs aro...

A photophysical study is reported for the trinuclear copper(I) complex {[3,5-(CF3)2Pz]Cu}3. The neutral compound exhibits multicolor bright phosphorescent emissions both in the solid state and in solution. The emission can be tuned to multiple visible colors by controlling the temperature, solvent, and {[3,5-(CF3)2Pz]Cu}3 concentration, giving rise to luminescence thermochromism, luminescence s...
