| Popis: | A series of new ‘inclusion’ materials based on tetra-4-methoxyphenyl, tetra-4-hydroxyphenyl and tetra-4-chlorophenyl derivatives of the metalloporphyrin system, in combination with a wide variety of guest molecules and ligands, have been prepared, and their structural systematics analysed. Crystallographic investigations have confirmed that the supramolecular arrangement of the hydroxyphenylporphyrin species is dominated by interporphyrin directional hydrogen-bonding interactions, and consists of continuous networks of strongly coordinated entities with varying degrees of cross-linking and rigidity. Guest molecules can be absorbed in these solids in distinctly defined sites of the lattice: in the small interhost cages of fixed size between adjacent intercoordinated porphyrin hosts, or in extended one-dimensional channels formed between the hydrogen bonded host arrays running parallel or perpendicular to the porphyrin plane. For polar ligands with strong nucleophiles, their potential coordination ... |
