A set of pushâpull ynamides with up to four conjugated triple bonds has been synthesized and the molecular properties of these new carbon rods have been characterised showing effective intramolecular charge transfers and high values for the change of the electrical dipole moment after transition from the ground to the FranckâCondon excited state.
我们合成了一组具有多达四个共轭三键的推拉namides,并对这些新型碳棒的分子特性进行了表征,结果表明,从基态过渡到弗朗克康顿激发态后,分子内电荷转移有效,电偶极矩的变化值也很高。
