Monolayer behavior of a rare-earth bisphthalocyanine derivative and determination of its molecular orientation in an LB film

Abstract

In this paper, the monolayer behavior of a new symmetrically substituted ytterbium bisphthalocyanine derivative Yb-octa-4-(2,4-di-tert-pentylphenoxyl) bis phthalocyanine was investigated, its phase change morphology at the air/water interface was directly observed by Brewster Angle Microscopy (BAM). Its molecular orientation in an LB film was determined by polarized UV–Vis spectra.
