Özet

Clockwise and anticlockwise dislocation operation on cyclacenes were defined. Certain types of dislocated cyclacenes were subjected to AMI type semiempirical molecular orbital calculations in order to get some idea about these nonexistent structures. They were predicted to be more stable than the isomeric cyclacenes. The cryptoannulenic effect, which is the characteristic feature of the cyclacenes. subsides or disappears depending on the type of the dislocated system. (C) 2001 Elsevier Science B.V.
