A C3-symmetric π-conjugated macrocycle combined with an appropriate hydrogen bonding module (phenylene triangle) allowed the construction of crystalline supramolecular frameworks with a cavity volume of up to 58%. The frameworks were obtained t

We designed and synthesized A2B2 type tetraphenyl benzene monomers (p-, m-, and o-TetPB) which have the para-, meta, and ortho-substituted isomeric structures, for the direct construction of isomeric frameworks. Interestingly, both kagome (kgm) and monoclinic square (sql) framework isomers are produced from either p-TetPB (C2h symmetry) or m-TetPB (C2v symmetry) by changing reaction solvents, while their isomeric structures are characterized by X-ray diffraction, computational simulation, microscopy, and sorption isotherm measurements. Only sql frameworks was formed for o-TetPB (C2v symmetry), irrespective of reaction solvents. These results disclose a unique feature in the framework structural formation, that is, the geometry of monomers directs and dominates the lattice growth process while the solvent plays a role in the perturbation of chain growth pattern. The isomeric frameworks exhibit highly selective adsorption of vitamin B12 owing to pore shape and size differences.

(Chemical Equation Presented) A novel, elegant, and significantly improved protocol for the synthesis of a protected octaacetylene phthalocyanine is described. Inexpensive, mild, and environmentally benign iodination of 1,2-dibromobenzene and subsequent optimized chemoselective palladium-catalyzed cyanation are employed to effectively build up the key intermediate 4,5-dibromophthalonitrile in two steps. Introduction of the tert- butyldimethylsilyl-protected acetylene moieties via a Sonogashira cross-coupling provides the desired phthalonitrile precursor that, after cyclization, yielded the protected octaacetylene phthalocyanine. Subsequently, in situ deprotection and "clicking" are employed as a highly efficient and quantitative route to a novel class of octatriazole-functionalized phthalocyanines. The ability of such triazole-derived phthalocyanines to form well-defined supramolecular structures upon doping with zinc(II) triflate is demonstrated.
