Modulation of Supramolecular Interaction of Pt(II) Complexes Bearing Carbene Cyclometalate for Color-Tunable Luminescence.

ABSTRACT: Pt(II) complexes are known for their versatility in showing aggregation-induced emission. Herein, we report four Pt(II) complexes Pt-1, Pt-2, and Pt-3a/b featuring both the carbene cyclometalate (C^C) and chelating pyrazolate (N^N). We evaluated two synthetic methods: the first employed the carbene intermediate Pt-DMSO, followed by N^N coordination to give Pt-1-Cl and aryl cyclometalation, while the second involved sequential addition of C^C and N^N chelates to Pt(COD)Cl₂. These Pt(II) complexes exhibited efficient sky-blue emission in a PMMA matrix at high dilution. Upon increasing the doping ratio, emission of Pt-1 and Pt-3a remained essentially unchanged, but Pt-2 and Pt-3b exhibited gradual emergence of a low-ene
