    摘要: A terrylene compound of formula I: wherein R1 to R4 are each independently an unsubstituted or substituted alkyl, aryl, thiophenyl or oligothiophenyl group, or a hydrogen atom. Two adjacent radicals selected from R1 to R4, 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.

    摘要: A method and an apparatus for maintaining information security in a video multicasting service are provided. The method includes: generating a network abstraction layer unit using received video information; encrypting the network abstraction layer unit of the video information; realtime transport protocol (RTP) packetizing the encrypted network abstraction layer unit of the video information; recording unit format information and field information, included in the network abstraction layer of the video information being stored in a memory, in a header extension field of the RTP header; and transmitting the RTP packet including the encrypted video information to a routing device.
