Abstract

Three chloroplatinum(II) complexes of 2,6-bis(benzimidazol-2′-yl)pyridine bearing hexaethylene glycol methyl ether are almost nonemissive in dilute aqueous solutions. Upon addition of excessive hexafluorophosphate salts to their dilute aqueous solutions, one of them was found to show a remarkable luminescence enhancement.
