Reactions of [Ir((CN)-N-boolean AND)(2)Cl](2) [HCYN = 2-(3-R-phenyl) pyridine, 2-(3-R-phenylpyrazole) R = H, Me] with Me-2-phencat give luminescent complexes [Ir((CN)-N-boolean AND)(2)(Me-2-phencat)][PF6] (Me-2-2a, b, c)[PF6]. Deprotection of the methoxy groups with BBr3 is problematic as simultaneous bromination of the cyclometallated phenyl groups occurs. However, deprotection of Me-2-phencat with BBr3 followed by complexation with [Ir(CYN)(2)Cl](2) gives luminescent complexes [Ir((CN)-N-boolean AND)(2)(H-2-phencat)][PF6] (H-2-3a, c)[PF6], which are luminescent sensors for molybdate.
