The synthesis and optical properties of four new triarylboraneâdipyrromethane (TABâDPM) conjugates (3aâd) containing dual binding sites (hydrogen bond donor and Lewis acid) have been reported. The new compounds exhibit a selective fluorogenic response towards the Fâ ion. The NMR titrations show that the anions bind to the TABâDPM conjugates via the Lewis acidic triarylborane centre in preference to the hydrogen bond donor (dipyrromethane) units.
