The syntheses, structures, and photophysical properties of a series of iridium(III) bis(2-pyridyl)phenyl complexes, (ppy)2Ir(LX) (LX = amide ligands), are described. The complex (ppy)2Ir(N-phenylmethacrylamide) (5), bearing an acrylamidate ligand, has been further employed for polymerization to generate the metal-containing homopolymer poly((ppy)2Ir(N-phenylmethacrylamide)) (6). In addition, the complexes (ppy)2Ir(acetylaniline) (2) and (ppy)2Ir(N-phenylbenzamide) (3) have been structurally characterized by X-ray crystallography. It was found that the amidate ligand binds to the Ir center in an imine/alkoxide mode via a four-membered, nearly planar ring (N−Ir−O−C); the limited delocalization is supported by the lengthened C−O bond compared to the C−N bond length in the amidate backbone and no strong absorption around 1650 cm−1 in the infrared spectra. The photophysical and electrochemical properties of these complexes were then studied. The maximum emission wavelengths ranging from 510 to 548 nm as well as the ΔE p values varying from 2.55 to 2.77 V can be attributed to the different effects of ancillary amide ligands tolerating different electronic characters. The HOMO and LUMO energy levels and compositions of the iridium complexes were investigated by DFT calculations. The amidate ancillary ligands affect the absorption and emission energies of these complexes by tuning the HOMO energies.

“…However, they are generally insoluble and infusible after conversion from their poly(amic-acid) precursors to polyimdes (3)(4)(5). Replacement of polyimides by copolyimides such as poly(amide-imide)s (PAIs) may be useful to tackle the intractability of polyimides (6)(7)(8)(9). PAIs are also expected to have the advantages of polyamides and polyimides, such as solvent resistance.…”

Five new optically active aromatic poly(amide-imide)s (PAIs) 5a-e were prepared from a direct polycondensation reaction of a new diacid of N,N -(bicyclo[2,2,2]oct-7-ene-2,3,5,6-tetra carboxylic)-bis-L-isoleucine 3 with various aromatic diamines 4a-e in a medium consisting of triphenyl phosphite (TPP), calcium chloride (CaCl 2 ), pyridine (Py) and N-methyl-2-pyrrolidone (NMP). The polycondensation reaction produced a series of novel poly(amid-imide)s 5a-e in quantitative yields with inherent viscosities of 0.39-0.51 dL/g. The resulting polymers were fully characterized by means of 1 H-NMR, FT-IR spectroscopy, elemental analyses, inherent viscosity, solubility test, specific rotation and thermal properties of them were investigated using TGA/DTG and differential scanning calorimeter (DSC). The diacid 4 was synthesized by the condensation reaction of bicyclo[2,2,2]oct-7-ene-2,3,5,6-tetracarboxylic dianhydride 1 with L-isoleucine 2 in acetic acid solution.
