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 solids.
Metalloporphyrins are exceedingly useful building blocks for the design and synthesis of molecularly based solids. The use of hydrogen bonding or metal ion coordination provides a wide range of framework solids. Using various polyfunctionalized porphyrins, we have created porous solids that are thermally robust and that retain their internal porosity upon loss of solvates. Their pore dimensions...
متن کاملCrystal engineering of nonporous organic solids for methane sorption.
The low density polymorph of the well-known host p-tert-butylcalix[4]arene absorbs more methane than p-tert-pentylcalix[4]arene at room temperature and 1 atm pressure, but the order of absorption is reversed at 38 atm with p-tert-pentylcalix[4]arene absorbing more.
متن کاملRecent developments in robust microporous porphyrin solids
A review of the recent literature is presented which assesses the development of robust microporous porphyrin framework solids and their potential to perform selective sorption or heterogeneous shapeor size-selective catalysis. The review focuses only on those porphyrin solids whose porosity is robust, i.e. whose framework remains after the removal of solvates, as determined by thermal gravimet...
متن کاملCrystal engineering of organic and metal-organic solids: design, structure and properties
Crystal engineering has recently emerged as a method of choice for the design and the construction of both organic and metal-organic functional materials. Solid-state synthesis, of the most commonly studied aspects of crystal engineering, has been shown to provide access to molecular targets that are hardly obtainable using principles of conventional (i.e. solution-based) organic synthesis. Rea...
