A composition comprising a first material substituted with at least one group of formula (I) and a second material substituted with at least one group selected from groups of formulae (IIa) and (IIb): wherein: Sp
1
and Sp
2
are spacer groups; NB independently in each occurrence is a norbornene group that may be unsubstituted or substituted with one or more substituents; n1 and n2 are 0 or 1; m1 is 1 if n1 is 0 and m1 is at least 1 if n1 is 1; m2 is 1 if n2 is 0 and m2 is at least 1 if n2 is 1; Ar
1
represents an aryl or heteroaryl group; R
1
independently in each occurrence is H or a substituent; and * represents a point of attachment to the first or second material. The composition may be used to form a layer of an organic electronic device, for example the hole-transporting layer of an organic light-emitting device.
一种组合物,包括至少一个符合式(I)的基团替代的第一材料和至少一个选自符合式(IIa)和(IIb)基团的第二材料:其中:Sp1和Sp2是间隔基团;NB在每次出现时独立地是一个诺邦烯基团,可以是未取代的或取代的一个或多个取代基;n1和n2为0或1;如果n1为0,则m1为1,如果n1为1,则m1至少为1;如果n2为0,则m2为1,如果n2为1,则m2至少为1;Ar1代表芳基或杂环芳基;R1在每次出现时独立地是H或一个取代基;*代表连接到第一或第二材料的连接点。该组合物可用于形成有机电子器件的层,例如有机发光器件的空穴传输层。
