Reactivity of terthiophene monomers understood using computational chemistry and spectroscopy. |
| 초록 |
A variety of new bis(oligo(oxyethylene)styryl)sexithiophenes have been prepared by chemical oxidation of ether-substituted styrylterthiophenes. In all cases dimers are formed in high yields, rather than the expected polymers. In addition, although three different regioisomers can potentially be formed from such an oxidation, the isolable products are shown to consist of only the head-to-head regioisomer. Theoretical calculations on alkoxystyrylterthiophenes show that this can be understood in terms of an uneven electron spin density distribution. The structures and vibrational properties of this series of styryl-substituted sexithiophenes and their charged species have been further examined using resonance Raman spectroscopy. |
