Organometallic complexes for nonlinear optics. 41: Syntheses and quadratic NLO properties of 4-{4-(4-nitrophenyl)diazophenyl}ethynylphenylethynyl complexes
摘要:
The syntheses of [Au(C C-4-C(6)H(4)C C-4-C(6)H(4)N=N-4-C(6)H(4)NO(2))(PPh(3))] (3), trans-[Ru(C C-4-C(6)H(4)-C C-4-C(6)H(4)N=N-4-C(6)H(4)NO(2))Cl(dppm)(2)] (4), [Ru(C C-4-C(6)H(4)C C-4-C(6)H(4)N=N-4-C(6)H(4)NO(2))(dppe)(eta-C(5)Me(5))] (5), and [Ni(C C-4-C(6)H(4)N=N-4-C(6)H(4)NO(2))(PPh(3))(eta-C(5)H(5))] (6) are reported, together with a single-crystal X-ray diffraction study of 4. Quadratic nonlinearities for 3-6 and [Ru(C C-4-C(6)H(4)NO(2))(dppe)(eta-C(5)Me(5))] (7) have been determined at 1.064 mu m and 1.300 mu m by the hyper-Rayleigh scattering (HRS) technique, comparison to related complexes revealing that beta values increase on introduction of azo group and pi-system lengthening.
