Determination of the molecular orientation of a phthalocyanine derivative in a Langmuir–Blodgett film by polarized UV–VIS spectra
Abstract
Langmuir–Blodgett (LB) films of (p-carboxyphenoxy)-tri(2,4-di-tert-pentyl phenoxy) phthalocyanine copper(II)(asyCuPc) are prepared; the associated forms of the compound in chloroform solution and the particular orientation of asyCuPc molecular macrocycles in LB films is determined by polarized UV–VIS.
