Semi-empirical molecular orbital treatment at the level of AM1 and PM3 has been performed on the Huckel type cyclacenes. The effect of peripheral circuits on the stabilities and the interfrontier energy gaps of cyclacenes has been investigated.

AM1 treatment of monogermacyclacenes
Türker, Burhan Lemi (1998-03-01)
Semi-empirical molecular orbital treatment of monogermacyclacenes of two different types has been performed at the level of AM1 type calculations. The effect of germanium substitution is found to be moderately destabilizing but it becomes less pronounced in larger systems. The heats of Formation values of these classes of structures are endothermic and exhibit cryptoannulenic effect. Also some physicochemical properties of monogermacyclacenes have been estimated.
AM1 treatment of certain cyclophane-fused tetraazaporphyrins
Türker, Burhan Lemi (1999-04-01)
An AM1-type semiempirical molecular orbital treatment has been performed on certain [2(2)]-type cyclophane-fused tetraazaporphyrins. It has been found that within the isomeric set of structures the most and the least endothermic porphyrins are the ones having non-Hamiltonian and Hamiltonian cyclophane moieties respectively. On the other hand, the lowest HOMO and LUMO and the highest HOMO energies are possessed by the structures bearing Hamiltonian and non-Hamiltonian cyclophane moieties respectively, wherea...
AM1 treatment of silacyclacenes
Türker, Burhan Lemi (Informa UK Limited, 1997-01-01)
Semi-empirical molecular orbital treatment at the level of AM1 type has been performed on Huckel type silacyclacenes having arenoid rings (R) of 2-9. The first and second type cryptoannulenic effects are defined.
AM1 treatment of cyclophanes with vinylic bridges
Türker, Burhan Lemi (Informa UK Limited, 1999-01-01)
Semi-empirical molecular orbital treatment at the level of AM1 type has been performed on the cyclophanes having vinylic bridges. The Hamiltonicity of the cyclophanes is introduced. It has been found that within the isomeric set of these endothermic compounds, the least and the most endothermic ones are Hamiltonian and nonHamiltonian, respectively.
AM1 treatment of some [2(2)](1,4)-cyclophane-fused tetraazaporphyrins
Türker, Burhan Lemi (2000-09-18)
AM1-type semiempirical molecular orbital calculations at the level of RHF approach have bean performed on certain [2(2)](1,4)-cyclophane-fused tetraazaporphyrins having Be+2, Si+2, Si+4, Ge+2, Ge+4 and Zn+2 as the central ions. The geometries, stabilities and the frontier molecular orbital energies were discussed.
