Triarylborane–dipyrromethane conjugates bearing dual receptor sites: the synthesis and evaluation of the anion binding site preference?
Dalton Transactions Pub Date: 2013-12-02 DOI: 10.1039/C3DT52565A
Abstract
The synthesis and optical properties of four new triarylborane–dipyrromethane (TAB–DPM) conjugates (3a–d) containing dual binding sites (hydrogen bond donor and Lewis acid) have been reported. The new compounds exhibit a selective fluorogenic response towards the F? ion. The NMR titrations show that the anions bind to the TAB–DPM conjugates via the Lewis acidic triarylborane centre in preference to the hydrogen bond donor (dipyrromethane) units.
