Abstract

In this article, we have demonstrated the promising separation methods for hydrothermally obtained fluorescent molecule formed from citric acid and 1,2-ethylenediamine. This fluorophore is a derivative of citrazinic acid and is known as a 1,2,3,5-Tetrahydro-5-oxo-imidazo[1,2-A]pyridine-7-carboxylic acid (IPCA). Gel electrophoresis and dialysis were applied for the extraction the fluorophore from start materials. IPCA molecule has strong absorption at 350 nm and luminescence at 450 nm with a high quantum yield of around 85±5%. The structure of the fluorophore and polymer-like structures was researched by spectrophotometry, spectrofluorimetry, IR and NMR spectroscopy.
