Provisional Recommendations

Nomenclature for Rotaxanes

Expanded definitions of rotaxanes, their components, and other terms concerning rotaxanes are given. The classification of rotaxanes and nomenclature principles for naming of different types of rotaxanes are described and illustrated with examples. Recommendations are provided for unambiguous description of rotaxane isomerism with special descriptors that include information about the position and orientation of rotaxane components.

This document includes the following main parts:

1. definitions of terms used in rotaxanes:

a. rotaxane itself,
b. rotaxane components,

    i. threading component and linear section
    ii. macrocyclic component and threadable ring

c. molecular shuttles and recognition sites

2. history of the nomenclature of rotaxanes
3. classification of rotaxane types
4. generic name format for rotaxanes
5. types of rotaxane isomerism and description of the location of simple macrocyclic components at different linear sections of a complex threading component and location of simple threading components in macrocyclic components with several threadable rings
6. types and specification of rotaxane stereo isomerism orientation of rotaxane components in relation to each other
7. examples of rotaxanes and recommended names
