Crystal engineering of porphyrin framework solids.
This article describes recent achievements made by us and other groups in targeted synthesis of porphyrin-based framework solids by various non-covalent mechanisms of molecular recognition. The self-assembly processes are effected in a tunable manner either by direct association of suitably designed porphyrin building blocks, or by their supramolecular aggregation through external linkers as me...
متن کاملMicroporous Porphyrin and Metalloporphyrin Materials
The diverse e4orts to rationally construct microporous solids using porphyrins and metalloporphyrins as molecular building blocks are reviewed. Porphyrin-based molecular crystals, hydrogen-bonded networks, and metal ion coordination polymer networks are examined in detail. Recurring geometrical motifs observed in the structural frameworks of di4erent porphyrinic solids are emphasized, and the i...
متن کاملNetwork diversity through decoration of trigonal-prismatic nodes: two-step crystal engineering of cationic metal-organic materials.
During the past decade porous metal–organic material (MOM) networks constructed from metal-based nodes (metal ions or metal clusters) and bridging organic ligand (linkers) have attracted ever increasing scientific interest. Their modular nature imparts structural and compositional diversity, tunable functionality, and multiple properties within a single material. In particular, that MOMs can ex...
متن کاملLiquid Crystal Materials and Liquid Crystal Displays
Since the early 1970s, three major prerequisites have brought the success of the liquid crystal display (LCD) technology to its key role of today. Namely, the discovery of electro-optical field-effects on which the displays are based, the successful search for liquid crystals (LCs) with material properties that meet the complex requirements of electro-optical effects and render the effects appl...
متن کاملCrystal structure of meso-tetrakis(4-nitrophenyl)porphyrin nitrobenzene disolvate
The porphyrin core of the title centrosymmetric compound, C44H26N8O8·2C6H5NO2, is approximately planar, the maximum deviation being 0.069 (3) Å. The planes of the benzene rings of the nitro-phenyl substituents are almost perpendicular to the porphyrin mean plane, making dihedral angles of 73.89 (9) and 89.24 (9)°. The two pyrrole ring H atoms are equally disordered over the four pyrrole ring N ...
