materials. In particular, devices based on radical dimerization are appropriate because of the effectiveness and speed of carbon–carbon bond making/breaking. Phenylmethylenepyrans are organic chromophores which are well suited for such purposes since their oxidation leads to the reversible formation of bispyrylium species by radical dimerization. In this paper, we show that the redox and spectroscopic properties
电致变色有机体系在电子刺激下可能会发生光学性质的显着变化,这对功能材料的开发引起了极大的兴趣。尤其是,基于自由基二聚化的设备是合适的,因为
碳-
碳键的形成/断裂的有效性和速度非常快。
苯基亚
甲基吡喃是有机发色团,由于其
氧化作用会通过自由基二聚作用可逆地形成双
吡咯类,因此非常适合用于此类目的。在本文中,我们证明了
苯甲基吡喃的
氧化还原和光谱性质可以通过DFT计算的支持,通过适当改变
苯基部分对位上的取代基来调节。
