Synthesis, characterization, and second-harmonic generation studies of surfactant rhenium(I) diimine complexes in Langmuir-Blodgett films. X-ray crystal structure of fac-ClRe(CO)3L (L = 9-heptylamino-4,5-diazafluorene)

A series of surfactant complexes of general formula, fac-CIRe(CO)3L (L = 9-octadecylamino4,5-diazafluorene, 9-(4′-hexadecylanilino)-4,5-diazafluorene, N-(4′-hexadecylphenyl)pyridine2-carbaldimine, and 9-heptylamino-4,5-diazafluorene), were synthesized and characterized by elemental analyses and 1H NMR, UV-vis, IR, and luminescence spectroscopy. The complex fac-CIRe(CO)3L (L = 9-heptylamino-4,5-diazafluorene) was structurally characterized. The formation and optical properties of their Langmuir-Blodgett (LB) films were studied by surface pressure-area (π-A) isotherms and UV-vis and luminescence spectroscopy, and the second-harmonic generation (SHG) behavior was also investigated.link_to_subscribed_fulltex
