ABSTRACT:
A crystalline molecular sieve is synthesized as encapsulating chelating agents which are macrocyclic organic molecules containing from about 8 to about 18 members in cyclic configuration with at least one bicyclic bridge having from about 3 to about 10 members, the molecule members being carbon, nitrogen, oxygen, sulfur, selenium, phosphorus and/or arsenic. The molecules contain at least two nitrogen members and at least one member is oxygen, sulfur, selenium, phosphorus, and/or arsenic, and the members include sufficient bonds to contiguous members or to hydrogen to form stable molecules. The macrocycles may be complexed with metal ions and the molecular sieve may be used in catalysis and medical imaging.
