Dimethylaminobenzoic Acid

Four adducts of triphenylphosphine oxide with aromatic carboxylic acids have been synthesized and tested for second-order non-linear optical properties. These were with N-methylpyrrole-2-carboxylic acid (1), indole-2-carboxylic acid (2), 3-dimethylaminobenzoic acid (3), and thiophen-2-carboxylic acid (4). Compound (1) produced clear, colourless crystals (space group P 212121 with a 9·892(1), b 14·033(1), c 15·305(1) Å, Z 4) which allowed the structure to be determined by X-ray diffraction.

The title compound, C23H12N4O, has potential application in non-linear optics; it has a chiral crystal structure despite the lack of a stereogenic centre. The crystal structure involves two intermolecular C—H...N hydrogen bonds.

The cubic hyperpolarizabilities of 1,3,5-(trans-[RuCl(dppe)2(C≡CC6H4-4-C≡C)])3C6H3 (1), 1,3,5-(trans-[Ru(C≡CPh)(dppe)2(C≡CC6H4-4-C≡C)])3C6H3 (2), 1,3,5-(trans-[Ru(C≡CC6H4-4-NO2)(dppe)2(C≡CC6H4-4-C≡C)])3C6H3 (3), 1,3,5-{trans-[Ru(C≡C-3,5-(trans-[Ru(C≡CPh)(dppe)2(C≡CC6H4-4-C≡C)])2C6H3)(dppe)2(C≡CC6H4-4-C≡C)]}3C6H3 (4), and 1,3,5-{trans-[Ru(C≡C-3,5-(trans-[Ru(C≡CC6H4-4-NO2)(dppe)2(C≡CC6H4-4-C≡C)])2C6H3)(dppe)2(C≡CC6H4-4-C≡C)]}3C6H3 (5) have been assessed over the spectral range 520–1600 nm using the Z-scan technique and ~150 fs pulses. All complexes exhibit negative values of γreal (corresponding to self-defocusing behaviour) and significant positive values of γimag (corresponding to two-photon absorption) at short wavelengths (up to 1000 nm). The maximal values of γreal and γimag increase in magnitude on dendrimer generation increase (proceeding from 2 to 4 or 3 to 5). The open-aperture Z-scan results have been used to confirm and contrast the two-photon (2PA) and three-photon absorption (3PA) behaviour of 1–5, the data being consistent with the existence of 2PA at the short wavelength range, but with significant 3PA at longer wavelengths for 1–3 and 5, a record 3PA coefficient for an inorganic complex for 5 at 1180 nm, and appreciable 3PA at the telecommunications wavelength of 1300 nm.
