of oligomeric lactones, namely tetra- and hexasalicylides 1 and 2, was synthesized from various halogenated salicylic acids by a cyclocondensation reaction using POCl3. The clathrate inclusion properties of the macrocycles for some organic solvents were investigated. X-ray structures of several representative clathrates in this series were determined and the results were used to explain various features

Some novel tetra- and hexasalicylide derivatives were synthesized. The tetrasalicylides having a 5-substituted halogen atom on the aromatic ring form organogels with several kinds of organic solvents, whereas the parent compound does not. In contrast, hexasalicylides form stable inclusion crystals with several organic guest molecules.
