4) Quinonoid Zwitterions: Synthesis, Coordination Chemistry, Deposition on Surfaces and Electronic Properties
A new class of potentially antiaromatic 12 p-electron zwitterionic organic quinonoid dyes was discovered in 2002. Their unprecedented electronic structure and properties have led to numerous developments in molecular chemistry and to fruitful collaborations with physicists, in particular for the tuning of the electronic properties of their self-assembled thin layers on various metal surfaces.
