Bulking Up the Bay-Position Substituents Enables Enhanced Selectivity of Cs-Symmetric Boron Subphthalocyanine–Subnaphthalocyanine Hybrids

“…This templated cyclotrimerization also encompasses mixed cyclotrimerization (also referred to as statistical cross-condensation or cocyclization) of two different o -dinitrile precursors to access new diiminoisoindole-hybridized analogues with fundamentally different physicochemical properties. Mixed cyclotrimerization typically forms hybrid BsubPc macrocycles with lower molecular symmetry (e.g., C s symmetry) and altered spectroscopic properties. ,− This approach has been further applied for the preparation of π-extended BsubPc hybrids with two-oxygen-bridged aromatic fragments, pyrene-fused diiminoisoindole units, core-expanded inner pyrrolic rings, − and benzo-annulated units. − …”
