  "id": "MLC-T-CHM-001738",
  "term": "Catenanes",
  "field": "Chemistry",
  "definition": "Compounds in which two or more rings are interlocked like links of a chain with no covalent bond between the rings, so they cannot be separated unless a covalent bond in one ring is broken. The simplest case has two interlocked rings, and chains of three or more rings are also known. They are made by template-directed synthesis and serve as building blocks for switchable molecular systems.",
