Reactions of Ir(C^N)(2)Cl [HC^N = 2-(3-R-phenyl)pyridine, 2-(3-R-phenylpyrazole) R = H, Me] with Me(2)-phencat give luminescent complexes [Ir(C^N)(2)(Me(2)-phencat)][PF(6)] (Me(2)-2a, b, c)[PF(6)]. Deprotection of the methoxy groups with BBr(3) is problematic as simultaneous bromination of the cyclometallated phenyl groups occurs. However, deprotection of Me(2)-phencat with BBr(3) followed by complexation with Ir(C^N)(2)Cl gives luminescent complexes [Ir(C^N)(2)(H(2)-phencat)][PF(6)] (H(2)-3a, c)[PF(6)], which are luminescent sensors for molybdate.
Ir(C^N)(2)Cl [HC^N = 2-(3-R-苯基)吡啶，2-(3-R-苯基吡唑)，R = H，Me]与 Me(2)-phencat 的反应生成发光配合物 [Ir(C^N)(2)(Me(2)-phencat)][PF(6)] (Me(2)-2a，b，c)[PF(6)]。用 BBr(3)脱甲氧基存在问题，因为同时会发生环金属化的苯基溴化。然而，用 BBr(3)脱甲氧基后再与Ir(C^N)(2)Cl络合，得到发光配合物[Ir(C^N)(2)(H(2)-phencat)][PF(6)] (H(2)-3a，c)[PF(6)]，它们是钼酸盐的发光传感器。
