Chromism of cyclometalated platinum(II) complex with picolinic acidderivative

摘要

Chromic materials show color change in response to external stimuli,expected to beapplicable to sensors.Particularly,square-planar platinum(II) complexes can exhibitinteresting chromic behavior by changes in Pt-Ptand/or π-π interactions.In this work,we synthesized anovel platinum(II) complex with picolinic acidderivative [Pt~(II)(3tfmppy)(3-iso)] (H3tfmppy = 2-[3-(trifluoromethyl)phenyl]pyridine,H3-iso =isoquinoline-3-carboxylic acid),(Figure 1),andinvestigated its chromic behavior.
