“…2 Fluorescein is widely used as a standard molecule for calculating the quantum yield, 3 and it exhibits a wide array of applications known to mankind. [4][5][6][7][8][9][10][11][12][13] One of the notable members of the graphene family is graphene oxide (GO). 14 GO is known to form stable colloidal suspensions.…”

Fluorescence Sensor Performance of a New Fluorescein Derivate: [2‐Morpholine‐4‐(6‐chlorine‐1,3,5‐s‐triazine)‐amino]fluorescein

“…During the past years, fluorescein and its derivatives have been widely employed as molecular probes in chemical biology . More attention has been paid to aminofluorescein (AF) because it could specifically combine with the biomolecules at the site of –OH, –SH, and –COOH, which makes it a potential fluorescent probe.…”

Indium-Catalyzed Aromative Spiro Coupling of Quinones with Oxindoles for Highly Functionalized Xanthenes as Efficient Fluorophores

“…In this respect, development for the construction of 9-substituted xanthenes have been well described . The classical synthetic method used to produce fluorescein derivatives involves Friedel–Crafts reaction between resorcinol and phthalic anhydride in the presence of acid . Typical strategies include coupling of benzyne derived from 2-(trimethylsilyl)­phenyl trifluoromethanesulfonate with aryl aldehydes (Scheme A) and the Pd-catalyzed reaction between hydrazones and 1-bromo-2-(2-(bromomethyl)­phenoxy)­benzene (Scheme B) .…”
