Project Details Nomenclature for Rotaxane Polymers

Project No.:
Start Date:
15 June 2007
End Date:
01 October 2012
Division Name:


To elaborate the IUPAC interdivisional document on the nomenclaturerules for naming rotaxane polymers. Work on this document was startedearlier (project 2000-037-1-800)but was interrupted in 2004 to await the completion of the IUPACrecommendations for naming low-molecular-weight rotaxanes (project2002-007-1-800). Thiswas to avoid the appearance of discrepancies and inconsistenciesin the rules proposed in these closely-related documents.


The recommendations published by the Commission on Macromolecular Nomenclature [Compendium of Macromolecular Nomenclature. Blackwell Scientific Publications, Oxford (1991)] have dealt with regular single-strand organic macromolecules [Pure Appl. Chem. 2002, 74 (10): 1921-1956], regular single-strand and quasi-single-strand inorganic and coordination polymers [Pure Appl. Chem. 1985, 57, 149-168], copolymer macromolecules [Pure Appl. Chem. 1985, 57, 1427-1440], regular double-strand organic polymers [Pure Appl. Chem. 1993, 65, 1561-1580], irregular single-strand organic polymers [Pure Appl. Chem. 1994, 66, 873-889], and non-linear macromolecules, and macromolecular assemblies [Pure Appl. Chem. 1997, 69, 2511-2521].

The proposed document will provide recommendations for the nomenclature for macromolecular structures having a linear component that is encircled by, but not bonded to, a cyclic component (knotted structures will be excluded). As a class, these structures are called “macromolecular rotaxanes” or “rotaxane polymers”. As far as possible, the principles of nomenclature established in the IUPAC Recommendations: “Nomenclature for Rotaxanes” [project 2002-007-1-800] are to be followed in this document.


Oct 2011 – A draft of the provisional recommendations is submitted to public review comments until 31 March 2012 (provisional recommendations >> ..provisional/abstract11/vohlidal_310312.html)
