A highly selective fluorescent chemosensor for Hg2+ based on a squaraine–bis(rhodamine-B) derivative: Part II

A tricorn‐rhodamine fluorescent chemosensor for detection of Co2+ ions

“…The association constant for the formation of the complex was calculated using fluorimetric titration data, according to the Benesi–Hildebrand (B–H) Equation : where F max and F 0 are fluorescence intensities of TrisRh with saturated Co 2+ and without Co 2+ , respectively; F is the measured fluorescence intensity corresponding to [Co 2+ ].…”

Dual sensing performance of a rhodamine-derived scaffold for the determination of Cu2+ and Ce4+ in aqueous media

“…Considering this challenge, we have recently undertaken a research program to explore easily available chemosensor compounds that demonstrate high chromogenic/fluorogenic activity for hazardous cations and anions [50][51][52][53][54][55][56][57]. In this study, a new rhodamine 6G-based derivative coupled with a carbazole block to form a dual-function chemosensor that exhibits high sensitivity for the selective detection of Cu 2+ and Ce 4+ in organic-aqueous media was designed, synthesized and characterized.…”

“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.…”
