A push–pull unsymmetrical subphthalocyanine dimer

Design, synthesis and optical properties of unsymmetrical subphthalocyanine trimer connected by phloroglucinol via axial positions.

An unsymmetrical subphthalocyanine trimer consisting of three different subphthalocyanine units was synthesized. Its optical and physical properties were investigated by UV/Vis, fluorescence spectrometry, cyclic voltammetry and computations. Energy transfer from the non-substituted subphthalocyanine unit to the perfluorinated subphthalocyanine unit via a trifluoroethoxy substituted unit is sugg...

Subphthalocyanine-radiaannulene scaffold - a multi-electron acceptor and strong chromophore.

Two subphthalocyanine (SubPc) units and a perethynylated, alkyne-expanded radiaannulene (RA) were fused together by a four-fold Sonogashira reaction to give a compound exhibiting: (i) four reversible one-electron reductions, the first signalling good acceptor strength of the RA core itself, while the following three are a consequence of the entire scaffold, and (ii) intense light absorption tha...

Inclusion of C60 fullerene in a M3L2 subphthalocyanine cage.

Synthesis of meso-substituted subphthalocyanine-subporphyrin hybrids: boron subtribenzodiazaporphyrins.

The first syntheses of hybrid structures that lie between subphthalocyanines and subporphyrins are reported. The versatile single-step synthetic method uses a preformed aminoisoindolene to provide the bridging methine unit and its substituent while trialkoxyborates simultaneously act as Lewis acid, template, and provider of the apical substituent. The selection of each component therefore allow...

Integration of inherent and induced chirality into subphthalocyanine analogue

Conventional conjugated systems are characteristic of only either inherent or induced chirality because of synthetic challenge in combination of chiral segment into the main chromophore. In this work, chiral binaphthyl segment is directly fused into the central chromophore of a subphthalocyanine skeleton, resulting in a novel type of chiral subphthalocyanine analogue (R/S)-1 of integrated inher...
