Synthetic dyes are generally made up by an electron acceptor (A) and an electron donor (D) group coupled by  or  bridges. The  bridge allows only the adiabatic coupling between A and D, a property that was advantageously used for the design of diodes and photodiodes at the molecular level. [1] We report herein the synthesis and characterization of a series of new chromophores based ona methanodibenzo[b,f][1,5]diazocine bridge (T), whose properties as charge carriers have not been yet explored. These chromophores, also known as Trögers bases (A-T-D), were synthetized as shown below. Trögers 1-4 have a common acceptor (A= CN) and a series of D with increasing electron donor capacity.
