SHG-active luminescent thermometers based on chiral cyclometalated dicyanidoiridate(iii) complexes.

ABSTRACT: Multifunctional optical materials can be realized by combining stimuli-responsive photoluminescence (PL), e.g., optical thermometry, with non-linear optical (NLO) effects, such as second-harmonic generation (SHG). We report a novel approach towards SHG-active luminescent thermometers achieved by constructing unique iridium(iii) complexes, cis-[Ir^III(CN)₂(R,R-pinppy)₂]^- (R,R-pinppy = (R,R)-2-phenyl-4,5-pinenopyridine), bearing both a chiral 2-phenylpyridine derivative and cyanido ligands, the latter enabling the formation of a series of molecular materials: (TBA)[Ir^III(CN)₂(R,R-pinppy)₂]·2MeCN (1) (TBA⁺ = tetrabutylammonium) and (n<
