Geometry and Steric Effects on the Electronic States of Aryl-o-Carboranes |
| 초록 |
o-Carborane was used to alter the electronic states of π-conjugated organic aryls, and demonstrated to be an effective electron controlling unit which can tune HOMO and LUMO energies for the electron transfer. Two different types of bis-aryl compounds were chosen to this end; one with di-phenyls and its fused fluorenyl and the other with two isomers of naphthyls, α- and β-forms. It has been found that among the series of aryl compounds the second type naphthyls were more susceptible to the electronic alteration and α-isomer of naphthyl showed the most perturbed electronic state. The ground state structures confirmed by the crystallographic measurements provided a close correlation of structure and electronic property in between photo-responsive aryl groups and o-carborane. Further to that distance effect, within the similar proximity of the aryl functional groups, namely naphthyl case, steric factor governed the change of electronic state. |
