L. Douce et al., Columnar mesophases from tetrahedral copper(I) cores and Schiff-base derived polycatenar ligands, CHEM COMMUN, (20), 1999, pp. 2033-2034
In the presence of copper(I), certain di- and tri-topic ligands derived fro
m reaction of substituted anilines with 2-pyridinecarbaldehyde or 2,6-pyrid
inedicarbaldehyde form a new type of polycatenar metallomesogen around the
tetrahedral metallic centre.
