Pipattanawarothai, Athit; Trakulsujaritchok, Thanida published the artcile< Hybrid polymeric chemosensor bearing rhodamine derivative prepared by sol-gel technique for selective detection of Fe3+ ion>, Recommanded Product: 2-(2-Aminoethyl)-3′,6′-bis(diethylamino)spiro[isoindoline-1,9′-xanthen]-3-one, the main research area is hybrid polymeric chemosensor rhodamine B derivative functionalized; ferric ion detection colorimetry.
To develop a reusable and selective colorimetric chemosensor for visual detection of ferric ion, a new rhodamine-based chelator (RB-UTES) was prepared The structural constitution and sensing property of RB-UTES were examined The chelator was sensitive and selective for recognition of ferric ion and could be covalently attached to poly(vinyl alc.) through siloxane linkage formed by the sol-gel reaction. The physicochem. properties and sensing behavior of the functional chemosensor films were studied. By simply soaking in aqueous media, the free-standing sensor film exhibited high selectivity and sensitivity to ferric ion and permitted the convenient detection by naked eye with prominent development of pink color throughout the film. The sensor film could return to its original color by washing with 0.1M ethylenediamine allowing repeated cycles of detection. The combination of its anal. performance, simplicity of operation as well as reusability made this functional sensor promising for the use in aqueous solutions and real samples.
