{{Non-free image rationale

| Article = Carceplex

| Purpose = To illustrate an example carceplex and the molecular mechanism of the function of a carceplex. Use in the article on carcerands is intended to provide general information in educational fair use. 1. not readily duplicated from free sources; 2. Image does not disclose any knowledge specific to the article in question and does not interfere with copyrighted use; 3. minimal usage, only relevant to linked article, clip is small snippet from larger work that also uses the image as illustrative of generalized concept; 4. published previously, Angew. Chemie.; 5. Encyclopedic- illustrates in a small image what would take hundreds of words to describe and would not be readily understood. Supports claim on page that carcerand is "hinged". 5. No known content problem; 6. No known media use problem; 7. This article; 8. illustrates in a small image what would take hundreds of words to describe and would not be readily understood; 9. 10. Description page should be complete and has copyright notice

| Replaceability = Complicated technical drawing that best visually illustrates the hinged nature of the molecule, not easily drawn as clearly and in a manner illustrative of link
