• Lewis‐Pairing‐Induced Electrochemiluminescence Enhancement from Electron Donor‐Acceptor Diads Decorated with Tris(pentafluorophenyl)borane as an Electrochemical Protector

  The feasibility of electrochemical protectors was demonstrated with a classical Lewis acid B(C6F5)3, which was mounted on donor-acceptor emitters to greatly stabilize electrogenerated radicals and enhancement of the Lewis-pairing-induced electrochemiluminescence (ECL). Electrochemical doping in segregated emitter-B(C6F5)3 co-assemblies afforded a crystalline film showing ECL through singlet exciton

  使用经典路易斯酸 B(C 6 F 5 ) 3证明了电化学保护器的可行性，将其安装在供体-受体发射体上，以极大地稳定电生成的自由基并增强路易斯对诱导的电化学发光 (ECL)。分离的发射极-B(C 6 F 5 ) 3共组件中的电化学掺杂提供了结晶薄膜，该薄膜通过源自柱状 π 堆叠的单线态激子离域显示出 ECL。
