Paper Abstract

Subphthalocyanines (SubPc) are composed of three isoindole units containing boron inside, which defines a molecular axis and forms a cone-shaped structure. Despite being non-planar, they show a delocalized 14(pi) -electron system similar to that present in phthalocyanines. The attractive characteristics of SubPc are their chemical stability and thermal stability. We report here the synthesis of three SubPc compounds, in which the axial substituent is a bromide. The peripheral substituent in the compounds leads to an improved solubility in common organic solvents. The results demonstrated that SubPc showed a strong and broad absorption region near 600 nm. This is advantageous for the purification and important for the applications in optical storage (DVD-R).
