    Notes: Liquid Crystals, 77[1]. - Novel Macroheterocyclic Palladium ComplexesThe double cyclopalladation of the bisimine 1 affords spacious tetrapalladium complexes 2a - c which represent new thermotropic metallomesogens, the heaviest low-molecular liquid crystals (mol. mass ≍ 3500 - 4000) studied so far.

    Liquid-crystalline Compounds, 86. The First Disc-Shaped Dinuclear Platinum Mesogen (1994)

    Notes: The cycloplatination of the tetrasubstituted imine 1 leads to the diplatinum organyl 3 as the main reaction product, which represents the first example of a new class of metallomesogens exhibiting monotropically a nematic-discotic phase. An X-ray crystal structure of this anti-isomer 3 has been performed. Furthermore, this platinomesogen also shows the induction of a hexagonal columnar mesophase (Dho) on doping with 2,4,7-trinitrofluorenone as an electron acceptor. Compared to the analogous palladomesogen the two mesophases observed are more stable in the case of the platinum liquid crystal.

    Inclusions between large flat organic molecules; the induction of columns and mesophases (1996)
    Springer
    Journal of inclusion phenomena and macrocyclic chemistry 24 (1996), S. 19-41

    Notes: Abstract We describe here an overview on the formation of mesophases by the interaction between large flat aromatic cored molecules and relatively small organic electron acceptors which form stacked, sandwich-like columnar π-π electron donor-acceptor complexes. The inclusion of suitable donor and acceptor components may be used to induce columnar mesophases in mixtures of compounds which can be either mesomorphic or non-mesomorphic in the pure state. With judicious choice of donor and acceptor partners, induced mesophases of remarkable range and thermal stability can be prepared.
