Abstract: Novel soluble μ-pheny l-tri (2,2-dimethylpropoxy) subphthalocyaninatoboron and μ-phenyl-tri (tert-butyl)-subnaphthalocyaninatoboron were prepared in this paper, and their spectral and aggregation properties were also studied. Our results indicate that the maximum absorption wavelength of SubNc is about 80 nm higher than that of SubPc, but both of them are blue-shifted about 100 nm compared with corresponding phthalocyanine and naphthalocyanine. Also, we find out that SubPc is stable, but SubNc is unstable to light. In addition, no aggregation in their solution takes place since the great spatialhindrance from the axial phenyl ring precludes molecular aggregation.

Key words: subphthalocyanine, synthesis, electronic absorption spectra, aggregation
