bidirectional synthesis, and we can now make a series of electron deficient anthracene, tetracene, and pentacene derivatives via the bidirectional iterative elongation protocol. Central units, used to initiate the bidirectional elongation, were synthesized by employing a double anionic Fries rearrangement as the key step. The photophysical and electrochemical properties of these novel electron acceptors
以前,我们开发了一种迭代伸长方法来合成并苯酯,腈和酰亚胺。该策略使用双向合成的概念,现在我们可以通过双向迭代延伸方案制备一系列缺电子的蒽,并四苯和并五苯衍生物。通过采用双阴离子Fries重排作为关键步骤,合成了用于引发双向伸长的中心单元。基于取代基的吸电子能力,研究和解释了这些新型电子受体的光物理和电化学性质。提出了一种化合物的激发态电荷转移,以说明其特殊的荧光行为。
