The [5.7] n cyclacenes represent a novel class of all sp 2 -hybridized carbon structures. In
contrast to the isomeric [n]cyclacenes, [5.7] n cyclacenes are predicted at the B3LYP/6-31G* …

… While [n]cyclacenes can be regarded as the shortest H-terminated (four-layered) (n,0) zigzag
carbon nanotube models, our computations show that cyclacenes with more than five fused …

Cyclacenes, C 4n H 2n , consist of n linearly fused benzene rings that are arranged to result
in a closed nanohoop structure. Cyclacenes are thus the cyclic versions of acenes and have …
