Rivaling the best one: Thermal [2+2] cycloadditions of TCNE, TCNQ, and F4‐TCNQ to N,N‐dimethylanilino‐substituted cyanoalkynes afforded a new class of organic super‐acceptors featuring efficient intramolecular charge‐transfer interactions. These acceptors rival the acceptor F4‐TCNQ in the propensity for reversible electron uptake as well as in electron affinity (see figure), which makes them interesting
竞争最好的一种是:TCNE,TCNQ和F 4 -TCNQ与N进行热[2 + 2]环加成反应,N-二甲基
苯胺基取代的
氰基
炔烃提供了新型的有机超级受体,具有高效的分子内电荷转移相互作用。这些受主在可逆电子吸收和电子亲和力方面都与受主F 4 -TCNQ竞争(见图),这使它们成为p型掺杂剂,在光电器件中有潜在的应用前景。
