文摘

A unidirectional ensemble of hemicyanine molecules was prepared by inserting the molecules into the verticalchannels of a uniformly oriented zeolite (silicalite-1) film grown on a glass substrate. Fluorescence from thissample excited with light polarized along the vertical channel was 50 times larger than that excited with lightpolarized orthogonal to the vertical channel direction. These vertically aligned hemicyanine dyes were usedto determine the ratio of the molecular hyperpolarizability components _zxx/_zzz of hemicyanine.
