Description
Emission and absorbance spectra of newly synthesized pyrrolopyrimidines were observed in different solvent environments. Pyrrolopyrimidines may exhibit excited-state intramolecular proton transfer (ESIPT) due to the proximity of a hydroxyl functional group to a ketone functional group. Three pyrrolopyrimidines were studied that have different substituents to see if the observed properties change with different electron donating abilities. The molecules, though similar in structure, exhibited different solvent effects on the fluorescence. If these pyrrolopyrimidines exhibit ESIPT, then these compounds would be excellent candidates for design of fluorescent sensors and other applications like laser dyes and organic light emitting devices.
