Z. Guo et al., Langmuir-Blodgett films and optical second-harmonic generation of a crowned [60]fulleropyrrolidine, APP PHYS B, 71(4), 2000, pp. 545-548
The Langmuir and Langmuir-Blodgett (LB) films of a novel crowned [60]fuller
o-pyrrolidine (CFP) were produced in different conditions. Macroscopic seco
nd-harmonic generation of the LB film was investigated by means of AM1 Hami
ltonian as well as experiments. The monolayer LB film displayed a periodic
fringe pattern. A linear dependence of second-harmonic intensity on the num
ber of layers was observed. The second-order molecular susceptibility chi((
2)) and hyperpolarizability beta were evaluated to be 3.2 x 10(-8) and 8.3
x 10(-29) esu.
