Abstract
Tetraphenyltetraethynylethene and the pi-acceptors 2,4,7-trinitrofluor en-9-one and (2,4,7-trinitro-9-fluoroenylidene)malononitrile form high ly ordered donor-acceptor pi-complexes having 1 : 2 stoichiometry in t he solid state; in solution, relatively weak 1 : 1 complexes are forme d whose stabilities are related to the spatial disposition of the dono r phenyl rings.
