Rhodamine 6G Based New Fluorophore Chemosensor Toward Hg²⁺

Abstract

All the reagents and solvents, used for synthesis of rhodamine 6G based dye sensor, were purchased from Aldrich and used without further purification.

Spectral Properties of a pH Responsive Water Soluble Spironaphthoxazine and Its Multi-Switching Property

“…Melting points were determined to use an Electrothermal IA 900 and are uncorrected. mixture solution was poured into 100 ml ether and precipitated; then filtered and washed with ether and 15,16) . Photochromic behavior of SPO in water is depicted as…”

Synthesis and Studies on Photophysical Properties of Rhodamine Derivatives for Bioimaging Applications

“…spirocyclic and open rings form. The spirocyclic forms (non‐fluorescent, colorless) exhibit limited π bond conjugated arrangement, whereas the open ring form (fluorescent, pink) shows exhaustive signals in the absorption and fluorescence spectroscopy due to extended large π‐conjugated systems . Rhodamine derivatives are massively used in the field of the bioimaging and biosensors because of their outstanding optical properties such as, quantum yield, molar absorption coefficient and photostability.…”

“Turn-on” fluorescent and colorimetric determination of Cu2+ ions in aqueous media based on a Rhodamine-N-phenyl Semicarbazide derivative

“…During recent years, our research group has focused on the design of new fluorimetric and colorimetric chemosensors for the recognition of various metal ions [40][41][42][43][44][45][46][47] and anions [48][49][50][51]. In this work, we report the design and synthesis of a novel rhodamine-based chemosensor (RGPS) through the reaction of rhodamine 6G hydrazide derivative and Nphenyl semicarbazide for the detection of metal ions in acetonitrile-aqueous (v/v, 9:1) media.…”
