A terrylene compound of formula I:
wherein R
1
to R
4
are each independently an unsubstituted or substituted alkyl, aryl, thiophenyl or oligothiophenyl group, or a hydrogen atom. Two adjacent radicals selected from R
1
to R
4
, together with the carbon atoms of the benzene ring to which they are bonded, may also form a fused ring system having 1 to 8 additional rings. With the carbon atoms to which it is bonded, A forms a fused monocyclic, dicyclic, tricyclic, tetracyclic, pentacyclic or hexacyclic ring system which optionally contains one or more independently selected substituents. A process for preparing the terrylene compound. An organic solar cell with a photoactive region including at least one organic donor material in contact with at least one organic acceptor material, the donor material and the acceptor material forming a donor-acceptor heterojunction, and the photoactive region including at least one such terrylene compound.
公式I的苯基化合物:其中R1至R4分别独立地是未取代或取代的烷基、芳基、噻吩基或寡噻吩基,或氢原子。从R1至R4中选择的相邻基团,与它们结合的苯环的碳原子一起,也可以形成具有1至8个额外环的融合环系统。与它结合的碳原子一起,A形成一个融合的单环、双环、三环、四环、五环或六环系统,该系统可以选择性地包含一个或多个独立选择的取代基。一种制备苯基化合物的方法。一种有机太阳能电池,其光活性区域包括至少一种有机给体材料与至少一种有机受体材料接触,给体材料和受体材料形成给受体异质结,光活性区域包括至少一种这样的苯基化合物。
