Organic electron acceptor materials play an important role in organic electronics. Recently, many organic electron acceptors have been developed, in which aromatic fused-imides have proved to be a promising family of excellent electron acceptors. We report the first synthesis of a novel aromatic fused-imide, acenaphtho[1, 2-k]fluoranthene diimide derivative (AFI), using lithium-halogen exchange and Diels-Alder reactions. The construction of a large conjugated plane and the introduction of electron-withdrawing imide groups endow AFI with a low lowest unoccupied molecular orbital (LUMO) level of -3.80 eV. AFI exhibits a regular molecular arrangement and strong ??-?? interactions in the single-crystal structure, which indicates its potential application in organic electronic devices. Solar cell devices that were fabricated using AFI as the electron acceptor and P3HT as the electron donor achieved an energy conversion efficiency of 0.33%.
Synthesis of two complementary molecular moulds

supporting information; experimental part, p. 1022 - 1026 (2009/07/19)
The synthesis of two complementary molecular moulds is described. These molecules comprise a polyaromatic central part and four lateral bulky tert-butylphenyl or di-tertbutylphenyl groups so that when they are deposited onto a surface, a cavity prone to metallic moulding is created.
Synthesis of aromatic carboxylic acids by carbonylation of aryl halides in the presence of epoxide-modified cobalt carbonyls as catalysts
Boyarskii,Zhesko,Lanina
, p. 1844 - 1848 (2007/10/03)
A new procedure was developed for synthesis of aromatic and heteroaromatic acids and their derivatives (esters, salts) by carbonylation of the corresponding aryl halides. The acids are selectively formed in a high yield under very mild conditions. Highly active catalytic systems, base-containing alcoholic solutions of cobalt carbonyl modified with epoxides, were used to activate aryl halides. 2005 Pleiades Publishing, Inc.
Reactions of 5,6-Dilithioacenaphthene-N,N,N',N'-Tetramethyl-1,2-ethanediamine Complex with α-Diketones. I. cis-Directing 1:1 Cyclic Additions with Acyclic and Cyclic α-Diketones and Related Compounds

The title complex (3) is readily generated from 5,6-dibromoacenaphthene with butyllithium and the diamine in ether at -10-0 deg C.The reaction of 3 with biacetyl gave cis-1,2,5,6-tetrahydro-1,2-dimethylcyclopent-acenaphthylene-1,2-diol but no trans-isomer, whereas the reaction of pyracenequinone (PYQ) with methylmagnesium bromide gave both the cis- and trans-diols.The reactions of 3 with acenaphthenequinone and PYQ also gave cis-diols.On treatment with phenylboronic, these cis-diols quantitatively yielded the corresponding cyclic esters.The diols and their derivatives tend to form crystalline molecular compounds with solvent molecules.The stereoselectivity of the cyclic addition between 3 and the acyclic α-diketone can be best explained in terms of five-membered chelate-ring formation in a transition state.
