Prikazan je sustav nomenklature na osnovi struktureza monocikličke i policikličke organske makromolekule. Obrađene su jednonitne (jednolančane) mono- i policikličke makromolekule kao i spiro-makrociklički spojevi. Nisu obuhvaćeni rotaksani i katenani koji sadrže prepletene prstenove i prstenove ili prstenaste sustave nastale nekovalentnim vezama. Polipeptidi i ugljikohidratni polimer itakođer su izostavljeni. Nomenklatura cikličkih makromolekula temelji se na postojećoj nomenklaturi pravilnih i nepravilnih makromolekula, a ta se temelji na nomenklaturi organske kemije koju je također objavio IUPAC. Postupak imenovanja cikličke makromolekule sastoji se u njezinu preoblikovanju u pravilnu ili nepravilnu otvorenu lančanu makromolekulu tako da se jedinice imenuju opadajućim redom seniornosti, a inače se primjenjuju pravila namijenjena za takve vrste makromolekula. Za policikličke makromolekule primjenjuju se ista načela nakon što se utvrde glavni prsten, mostovi i jedinice grananja te obilježe lokanti zajedinice grananja i mostove. Cjelokupna imena se oblikuju navođenjem imena komponenata i lokanata odgovarajućim redom u skladu s pravilima u ovom dokumentu. Gdje je god moguće, postupak imenovanja ilustriran je primjerima iz literature., A structure-based nomenclature system for monocyclic and polycyclic organic macromolecules is presented. Single-strand mono- and polycyclic macromolecules as well as spiro macrocyclic compounds are covered. However, rotaxanes and catenanes, which contain interlocked rings, and rings or ring systems formed by noncovalent bonds are excluded. Also, polypeptides and carbohydrate polymers are not included. The nomenclature of cyclic macromolecules is based on the existing nomenclature of regular and irregular macromolecules, which in turn is based on the nomenclature of organic chemistry also published by IUPAC. The procedure for naming a cyclic macromolecule consists of transforming it to an open-chain regular or irregular macromoleculein such a way that naming of units proceeds in descending order of seniority but otherwise follows the rules established for these types of macromolecules. For polycyclic macromolecules, the same principles are followed after the main ring, bridges, and branch units are identified and locants for branch units as well as bridges are assigned. The complete names are assembled by citing the component names and locants in the appropriate order according to the rules in this document. Wherever possible, examples for illustration of the naming procedure have been chosen from the literature.
