J. Hulliger et al., A SUPRAMOLECULAR APPROACH TO THE PARALLEL ALIGNMENT OF NONLINEAR-OPTICAL MOLECULES, Pure and applied optics, 7(2), 1998, pp. 221-227
A supramolecular synthesis utilizing perhydrotriphenylene (PHTP) as an
inclusion host compound has proven to be an efficient method of align
ing guest nonlinear optical (NLO) molecules in a parallel fashion. App
lication of Markov's theory of stochastic processes explains successfu
lly the experimentally observed spontaneous formation of polarity on a
macroscopic level.
