LANGMUIR-BLODGETT-FILM AND NONLINEAR-OPTICAL PROPERTY OF C-60-GLYCINE ESTER DERIVATIVE

Both the Langmuir and Langmuir-Blodgett films of two C-60-glycine ester derivatives, C-60(C60H9NO4) (1) and C-60(C8H13NO4) (2), have been prepared at the air/water interface. The Langmuir films can be readily transferred onto hydrophilic quartz substrates in Z type to form LB films. The LB film of 1 has good vertical homogeneity as indicated by UV-VIS spectra and a SHG study. The second- and third-order molecular hyperpolarizabilities beta and gamma have been determined to be (2.3 +/- 1.0) X 10(-29), 3.4 X 10(-31) esu for 1 and (1.9 +/- 0.8) X 10(-29), 3.3 X 10(-31) esu for 2, respectively.Chemistry, PhysicalPhysics, Atomic, Molecular & ChemicalSCI(E)30ARTICLE5-6548-55123
