Electroabsorption of metallophthalocyanines

摘要

Electroabsorption spectra have been measured on poly(methyl methacrylate) thin films doped with three kinds of metallophthalocyanines: tetrakis (tert-butyl) metal-free and lead phthalocyanines, and hexadeca (trifluoroethoxy) metal-free phthalocyanine. The third-order nonlinear optical susceptibility, $Chi$+(3)$/ ($MIN approximately ega@; approximately ega@, O, O), was determined from the electric field-induced absorption change. The considerable differences in absorption, electroabsorption, and complex $Chi$+(3)$/ ($MIN approximately ega@; approximately ega@, O, O) spectral profiles of these metallophthalocyanines are attributable to the difference in molecular aggregation states.
