Some substituted biaryl ring systems may be useful in light-emitting devices, such as those comprising a light-emitting diode. Some examples may include optionally substituted 2,2′-bipyridinyl or optionally substituted 3,3′-bipyridinyl. Each ring of these bipyridinyl systems may have an optionally substituted benzimidazol-2-yl substituent or optionally substituted benzoxazol-2-yl substituent, as well as other substituents.
一些替代的联苯环系统可能在发光器件中有用,例如包括发光二极管的器件。一些例子可能包括可选取代的2,2'-联吡啶基或可选取代的3,3'-联吡啶基。这些联吡啶系统的每个环可能具有可选取代的苯并咪唑-2-基取代基或可选取代的苯并噁唑-2-基取代基,以及其他取代基。
