Synthesis of a new tripodal chemosensor based on 2,4,6-triethyl-1,3,5-trimethylbencene scaffolding bearing thiourea and fluorescein for the chromo-fluorogenic detection of anions

A tripodal receptor containing thiourea as binding site and fluorescein as signalling subunit has been designed, synthesized and used for the colorimetric detection of basic anions in DMSO solutions. (C) 2012 Elsevier Ltd. All rights reserved.
