    Inversion of the Rectifying Effect in Diblock Molecular Diodes by Protonation
    摘要:
    A new molecular diode based on biphenyl-co-bispyrimidine was synthesized and showed a pronounced rectifying effect. Further studies indicate that protonation on the nitrogen atoms of the diode molecule by strong acids can reversibly alter the rectifying direction. This phenomenon can be envisioned as a starting point for single molecule detection devices.

    (TADF) materials, (5,5′-bis(4-(9,9-dimethylacridin-10(9H)-yl)phenyl)-2,2′-bipyrimidine (22bpmAc), 10,10′-([2,5′-bipyrimidine]-2′,5-diylbis(4,1-phenylene))bis(9,9-dimethyl-9,10-dihydroacridine) (25bpmAc), and 2,2′-bis(4-(9,9-dimethylacridin-10(9H)-yl)phenyl)-5,5′-bipyrimidine (55bpmAc)) based on bipyrimidine cores as the new electron-accepting units and acridine as the electron-donating unit were designed
    三种新型的绿色热激活延迟荧光(TADF)材料,(5,5'-双(4-(9,9-二甲基ac啶-10(9 H)-基)苯基)-2,2'-联嘧啶(22bpmAc), 10,10'-([[2,5'-bipyrimidine] -2',5-diylbis(4,1-phenylene))bis(9,9-dimethyl-9,10-dihydroacridine)(25bpmAc)和2 2′-双(4-(9,9-二甲基ac啶-10(9 H设计,合成了基于联嘧啶核作为新的电子接受单元和a啶作为供电子单元的)-基)苯基)-5,5'-联嘧啶(55bpmAc)),并将其用作TADF器件中的绿色发射体。TADF发射器设计为在联嘧啶核中具有不同的氮取向。相对于22bpmAc,两个发射器25bpmAc和55bpmAc显示出更高的量子效率和更窄的发射光谱。前者通过中心核上的氢键相互作用而具有受限的几何形状,而后者则没有氢键。
