Abstract
The disc-shaped tetra-palladium organyl 1 forms optically active charg e transfer complexes in equimolar mixtures with the enantiomers of the pi-acid electron acceptor 2, (+)- or (-)-TAPA, exhibiting lyotropic c holesteric nematic properties in apolar organic solvents. These ternar y systems are the first examples in which such a lyomesophase has been induced by charge transfer interactions.
