The alkynes HC≡CC6H2-2,6-Et2-4-C≡CC6H4-4-NO2 (4) and HC≡CC6H4-4-C≡CC6H2-2,6-Et2-4-C≡CC6H4-4-NO2 (6) and gold alkynyl complexes Au{C≡CC6H2-2,5-(OEt)2-4-C≡CC6H4-4-NO2}(PPh3) (7), Au(C≡CC6H2-2,6-Et2-4-C≡CC6H4-4-NO2)(PPh3) (8), and Au(C≡CC6H4-4-C≡CC6H2-2,6-Et2-4-C≡CC6H4-4-NO2)(PPh3) (9) have been synthesized. The linear optical properties and quadratic optical non-linearities of 7–9 have been measured, the latter by hyper-Rayleigh scattering at 1064 nm, and compared with data for the previously reported complexes Au(C≡CC6H4-4-NO2)(PPh3) (10) and Au(C≡CC6H4-4-C≡CC6H4-4-NO2)(PPh3) (11). The optical absorption maximum red-shifts and the first hyperpolarizabilities increase on π-system lengthening and on introduction of electron-releasing substituents on the π-bridge ring adjacent to the metal centre. The cubic non-linear optical properties of 1,4-{(PCy3)Au(C≡C)}2C6H4 (12) and {(PCy3)Au(C≡C-4-C6H4C≡C)}6C6 (13) have been assessed by wide spectroscopic range femtosecond Z-scan studies; the maximal values of the imaginary component and the effective two-photon absorption cross-section increase markedly on proceeding from linear complex 12 to 6-fold-symmetric complex 13, an increase that is maintained when data are scaled by relative molecular weight.

AbstractThe crystal structure and non-linear optical properties of L-alaninium perrhenate, C3H8NO2+ ReO4 −, are reported. The protonated amino acid and the perrhenate anion have their usual geometries. The three-dimensional hydrogen-bonded network can be seen as a stacking of layers parallel to the (100) planes. Each layer is formed by chains of alternating positive and negative ions along the b and c axes. Hydrogen bonding of adjacent layers forms alternating chains along the a axis. A high damage threshold and a second-harmonic generation efficiency three times that of KDP make this new material potentially useful in non-linear optics.

This work reports a method for electrodepositing sol–gel/CNT composite films. The deposition is highly selective to conductive surfaces, and the films exhibit non-linear optical properties and excellent antireflection performance.

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.
