Abstract
The condensation of amines of the general type H2N‐(CH2)n‐D‐(CH2)m‐NH2 (D is an aromatic system with electron donor properties) with 1,2:4,5‐benzene‐tetracarboxylic dianhydride or with 1,8:4,5‐naphthalene‐tetracarboxylic dianhydride under high dilution conditions is shown to lead to the formation of electron donor(D)‐acceptor(A) cyclophanes of the type magnified image containing the 1,2:4,5‐benzene‐tetracarboxylic diimide or the 1,8:4,5‐naphthalene‐tetracarboxylic diimide group as an electron acceptor.The fragmentation pattern of the cyclophanes upon electron impact is studied and found to agree completely with the proposed structures.Keywords
