There is considerable interest in the development of molecular arrays for long range electron transfer in view of applications in molecular electronics and solar energy conversion. 1,2 In this context, electronic communication via the bridging unit is essential for achieving fast and efficient electron transport over a long distance. Naphthalenebisimide (NBI) has many favorable properties as electron acceptor in such arrays, with a suitable reduction potential (–0.5 V vs. SCE) ...
