Electronic spectra and conformational states of mono- and diphenyl derivatives of [2.2]paracyclophane
Autor: Leszek Czuchajowski, Antoni K. Wisor
Publikováno v: Monatshefte für Chemie - Chemical Monthly. 114:1023-1034
Ultraviolet spectra of 4-phenyl-[2.2]paracyclophane and of the 4,7- and 4,13-diphenyl derivatives were interpreted. MINDO/3 total molecular energy andPPP—CI-1 energies of singlet transitions were calculated for different values of the dihedral angl

Electronic spectra ofsyn- andanti-ring [2.2]quinolinophanes
Autor: Maria J. Maślankiewicz, Antoni K. Wisor, Leszek Czuchajowski
Publikováno v: Monatshefte für Chemie. 112:1175-1185
The energies and oscillator strengths of the singlet-singlet transitions for thesyn- andanti-ring [2.2]quinolinophanes—regarded as quinoline dimers—were calculated usingPPP CI-1 method and compared with experimental spectra. The theoretical trans

The study of atropoisomers ofmeso-tetrakis[2.2]paracyclophanylporphyrin
Autor: Leszek Czuchajowski, Antoni K. Wisor, Stefan Goszczynski
Publikováno v: Journal of Heterocyclic Chemistry. 25:1343-1349
Theoretical considerations of atropoisomers of the title compound have revealed the existence of a large number of stable isomeric species. Syntheses, carried out according to two procedures at widely separated temperatures, resulted in the formation

Autor: Stefan Goszczynski, Tadeusz Malinski, Leszek Czuchajowski, Janet E. Bennett, Antoni K. Wisor
Publikováno v: Journal of Heterocyclic Chemistry. 26:1477-1484
Replacement of all phenyl groups in meso-tetraphenylporphyrin, TPP, by [2.2]paracyclophane, PCP, enhances the increase of energy of the HOMO and HOMO-1 of porphine, P, already noticed for the mono-[2.2]paracyclophanyl-substituted TPP, and fills the e
