Description
My research involves the synthesis and fluorescence study of a pH-sensitive Rhodamine B derivative via a two step process initially reacting Rhodamine B with hydrazine and ethanol under reflux to obtain Rhodamine B Hydrazide and later reacting this product with 4-formylbenzene-1,3-disulfonate under reflux to obtain the unnamed final product. The fluorescence spectra of this final product are taken at various pH values to verify that fluorescence intensity varies with pH. The goal of this project is to make a pH sensor by covalently bonding the Rhodamine B derivative to optical fibres.
