• Associated context:

  The electronic spectrum of the axially-disubstituted phenoxy-cyclotriphosphazenyl silicon phthalocyanine (5) showed an intense  Q absorption band at 684 nm in DMSO (Fig. 4). The spectra showed monomeric behavior evidenced by a single (narrow) Q band, typical of metallated phthalocyanine complexes for 5 in DMSO [32]. The B-bands were broad due to the superimposition of the B1  and B2 bands at around 350 nm (Fig. 4).
