Özet

A novel compound hexa-rhodamine substituted phosphazene (HRP) with six active centers on a cyclotriphosphazene ring was synthesized using the alkyne-azide "click" reaction. The structure of HRP was characterized using spectroscopic techniques. The optical sensor properties of HRP for metal ions were investigated using UV-Vis and Fluorescence spectroscopy. It was determined that HRP is a selective sensor with colorimetric and fluorescent properties for Fe3+ ions. Limit of detection (LOD) of HRP was determined as 6.94 x 10(-9) M using fluorescence intensities in the presence of different concentrations of Fe3+ ions. It was determined that HRP-Fe3+ complex has high quantum yield and excellent photostability.
