Compounds in the series from boron subphthalocyanine to boron subnaphthalocyanine

Abstract

The four compounds in the series from chloro[subphthalocyaninato]boron(III) to chlo-ro[subnaphthalocyaninato]boron(III) were synthesized in a one-pot reaction. To obtain a more soluble set of compounds, the mixture was then reacted with the sodium salt of trihexylsilanol. This mixture was separated by chromatography to provide trihexylsiloxy[subphthalocyaninato]boron(III), trihexylsiloxy[ Sub N 1 P 2 ]boron(III), trihexylsiloxy[ Sub N 2 P 1 ]boron(III) and trihexylsiloxy[subnaphthalocyaninato]boron(III). These compounds were characterized by 1 H NMR , EI-MS and UV-vis. They show interesting spectral features in the visible region.
