Macrocyclic Complexes of Boron: Subphthalocyanines

The subphthalocyanine (SubPc) macrocycles are lower homologs of the more familiar phthalocyanines (Pcs). They contain three isoindoline nitrogen atoms in the central core atoms that are bound to boron. The boron is also bound to an axial anionic ligand, typically Cl or Br. In contrast to the planar Pcs, the Subpcs are cone-shaped and the geometry about the central boron is approximately tetrahedral. Like the Pcs, the SubPcs are aromatic, although they have only 14-π electrons instead of the 18 found in the Pcs.

Like the Pcs, the Subpcs display both Soret-band and Q-band absorptions in their electronic spectra. The Q-band, however, is at 565 nm and as a result SubPc solutions are pink. Most recent work on the SubPcs has focused on their interesting second- and third-order nonlinear optical properties.6,7

The synthesis and spectroscopic properties of a series of SubPc adducts in which the axial halide ion is replaced with aromatic alcohols will be described. The redox properties of these compounds, studied using cyclic voltammetry will also be presented.
