PM3 treatment of certain catenanes having cyclacenes and cyclotriacontene units

Türker, Burhan Lemi
The results of PM3 (RHF) type semiempirical quantum chemical treatment of certain catenanes which consisted of all-trans cyclotriacontene shaft and the cyclacene shuttle, having R benzenoid rings (R = 6-9) were reported. The results have indicated that the cryptoannulenic effect which is the characteristic property of cyclacenes is almost lost when they are incorporated into the structures of catenanes considered.
