Synthesis and aggregation behavior of zinc phthalocyanines substituted with bulky naphthoxy and phenylazonaphthoxy groups: An experimental and theoretical study.

Highlights: [•] Zinc (II) phthalocyanines bearing bulky groups were prepared and characterized. [•] Aggregation properties of these compounds were investigated in THF. [•] Aggregation is limited with the solvent rather than bulky side groups. [•] DFT-D is necessary to describe the interactions between phthalocyanines. [ABSTRACT FROM AUTHOR]
