Facile tuning of the aggregation-induced emission wavelength in a common framework of a cyclometalated iridium(III) complex: Micellar encapsulated probe in cellular imaging

A simple synthetic protocol involving two steps was developed for the syntheses of a series of monocyclometalated iridium(iii) complexes. Initially, an intermediate, [IrHCl[(o-C6H3X)P(Ar) x-(PArxRy)2] [A (i, j, k, l)], six-coordinated iridium(iii) complex involving a 4-membered chelate was isolated. Then, it was transformed into a monocyclometalated iridium(iii) complex, [(C^N)Ir(PArx-1Ry)2(Cl(H)] (1-12), by the replacement of the 4-membered chelates with 5-membered cyclometalates. The intermediates and the complexes were structurally characterized by FTIR, 1H, 13C and 31P NMR spectroscopies. Octahedral coordination for Ir(iii) in 2, 8 and 9 was established by single crystal X-ray diffraction. Photo-physical experiments and quantum chemical calculations revealed a mixed LC/MLCT/LLCT nature for the lowest excited states of all these complexes that emit bright light in the solid state. Fine tuning of the emission wavelength throughout the visible range was achieved by suitable combinations of chromophoric cyclometalates and non-chromophoric aryl phosphine ligands. More interestingly, all the studied complexes were found to be aggregation-induced emission (AIE) active. One of these AIE active materials (6) was encapsulated inside polymeric micelles that inhibit the macroscopic precipitation of the aggregated complex, a strong emission. These colloidal luminescent particles were used as a potential non-toxic bio-imaging probe. This journal is the Partner Organisations 2014.

Ligand effects on luminescence of new type blue light-emitting mono(2-phenylpyridinato)iridium(III) complexes

Newly prepared hydrido iridium(III) complexes [Ir(ppy)(PPh 3)2(H)L]0,+ (ppy = bidentate 2-phenylpyridinato anionic ligand; L = MeCN (1b), CO (1c), CN- (1d); H being trans to the nitrogen of ppy ligand) emit blue light at the emission λ max (452-457, 483-487 nm) significantly shorter than those (468, 495 nm) of the chloro complex Ir(ppy)(PPh3)2(H)(Cl) (1a). Replacing ppy of 1a-d with F2ppy (2,4-difluoro-2-phenylpyridinato anion) and F2Meppy (2,4-difluoro-2-phenyl-m-methylpyridinato anion) brings further blue-shifts down to the emission λmax at 439-441 and 465-467 nm with CIE color coordinates being x = 0.16 and y = 0.18-0.20 to display a deep-blue photoemission. No significant blue shift is observed by replacing PPh3 of 1a with PPh2Me to produce Ir(ppy)(PPh2Me)2(H)(Cl) (1aPPh2Me), which displays emission λmax at 467 and 494 nm. The chloro complexes, [Ir(ppy)(PPh3)2(Cl)(L)]0,+ (L = MeCN (2b), CO (2c), CN- (2d)) having a chlorine ligand trans to the nitrogen of ppy also emit deep-blue light at emission λmax 452-457 and 482-487 nm.
