Abstract New crown compounds 3–5 comprising beside ophenylene groups 1, 8- naphthyridine or 4-pyridone groups as characteristic building units are synthesized. They form numerous stoichiometric crystalline complexes with uncharged organic molecules including alcohols, nitro compounds and other dipolar-aprotic solvents, as well as cyclic ethers and aromatic hydrocarbons. Properties of complex formation and host-guest ...
