Structural characterization of the mesophases exhibited by dicopper and diruthenium trialkyloxybenzoates
Binuclear Copper and Ruthenium complexes derived from long-chain 3,4,5-trialkyloxybenzoates (noted as B3OCn), namely Ru2(B3OCn)4Cl and Cu2(B3OCn)4 with n = 10, 12, 14, 16 and 18, were synthesized. The structure of their mesophases was characterized by X-ray diffraction. Both series exhibit low-tempe...

| Sumario: | Binuclear Copper and Ruthenium complexes derived from long-chain 3,4,5-trialkyloxybenzoates (noted as B3OCn), namely Ru2(B3OCn)4Cl and Cu2(B3OCn)4 with n = 10, 12, 14, 16 and 18, were synthesized. The structure of their mesophases was characterized by X-ray diffraction. Both series exhibit low-temperature liquid crystalline phases and, in particular, room temperature mesophases for the lower homologues of the ruthenium series. The mesophases exhibited by Ru2(B3OCn)4Cl were found to be hexagonal columnar (COlH) in nature, whereas the structure of the mesophases of the copper derivatives depends on the aliphatic chain length, being ColH for n = 10, 12, 14 and cubic for the longer homologues. |
