摘要：

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 (D(ho)) 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.
