A class of newly synthesizable pyrazolopyrimidine organic dyes observe fluorescence behavior due in part to a combination of excited state intramolecular proton transfer (ESIPT) and electron transfer (ET). Stoke’s shift of dyes range anywhere from 4800 to 8800 cm<sup>-1 </sup>and lifetime measurements of ESIPT yield anywhere from 1.0-2.9 ns. Some varieties of these molecules observe solvatochromism properties. Steady-state absorption, steady-state emission, and emission lifetime spectra reinforce these conclusions. These molecules could have applications in cutting-edge technology which includes use in molecular electronics and fluorescence sensing.
