Journal Textile Coloration and Finishing Year / Vol., Issue, Month 2014 / V.26,no.3,Sept Title Synthesis of Novel Fluorescent Dye Based on Fluorescein Authors Ji-yong Hwang and Young-A Son† Institution/Affiliations Chungnam National University Pages/Total page pp.272 ~ 276 / 5 Language English Abstract The functional materials have been developed as a promising research topic toward the end uses for organic materials and applications. In this study, fluorescein based dye was synthesized by three step reaction. We have designed and synthesized the colorimetric dye through the reactions of fluorescein and methoxy group and ethylene diamine and squaric acid. The structure of the non-fluorescent spirolactam was elucidated by 1H-NMR, LC-Mass and FT-IR analyzes. Further studies are in progress to understand the effects of various substituent during the recognition process and to develop fluorescein based sensors for cations or anions.
