摘要：

Poly(N-vinylcarbazole) layers containing tetra-5-crown-5-gallium phthalocyaninate (R4Pc)Ga(OH) are shown to possess photoelectric and photorefractive sensitivity at a wavelength of 1064 nm. This effect is associated with the formation of supramolecular ensembles of (R4Pc) Ga(OH) molecules with electronic optical absorption in the near-IR range and nonlinear optical properties. For the composite containing 5 wt % (R4Pc) Ga(OH) supramolecular ensembles, the dependence of the quantum efficiency of mobile-charge photogeneration on electric field E-0 is well fit by the Onsager equation expanded to E-0(3) at a quantum yield of electron-hole pairs of phi(0) = 0.9 s with an initial separation radius of r(0) = 9.8 angstrom. Third-order susceptibility. (3) equal to 1.85 x 10(-10) esu is measured via the well-known method of electric-field-induced second-harmonic generation. Two-beam-coupling gain coefficient G is found to be 80 cm(-1) at E-0 = 120 V/mu m.
