Composition having an organic semiconducting material and a triplet-accepting material of formula (I) with a triplet energy level lower than the triplet energy level of the organic semiconducting material, in which each Ar is optionally substituted aryl or heteroaryl group, n is 1-3, m is 1-5, q is 0 or 1, each R
3
is H or a substituent, and each R
4
is H or a substituent. Where R
4
is not H, R
4
and (Ar)
m
bound to the same carbon atom may be linked by a direct bond or a divalent group. Where n or m is at least 2, adjacent Ar groups may be linked by a divalent group. Where q=0, R
3
is not H and is linked to (Ar)
n
by a direct bond or a divalent group.
具有有机半导体材料和式(I)的三重子受体材料的组合物,其三重能级低于有机半导体材料的三重能级,其中每个Ar是可选取代基的芳基或杂环芳基,n为1-3,m为1-5,q为0或1,每个R3是H或取代基,每个R4是H或取代基。当R4不是H时,R4和(Ar)m与同一碳原子结合的可能通过直接键或二价基团连接。当n或m至少为2时,相邻的Ar基团可以通过二价基团连接。当q=0时,R3不是H,并且通过直接键或二价基团连接到(Ar)n。
