  Rhodium(I) and Iridium(I) Complexes Containing β-Diketonate or Pyrazole Ligands. Liquid Crystal and Nonlinear Optical Properties

  摘要：

  Square-planar rhodium or iridium "n-decyloxy-beta-diketonate" complexes of the general formula [M(beta-diketonate)(CO)(2)] (M = Ph (1-3) or Ir (4-6)) and pyrazole-rhodium derivatives of the type [RhCl(CO)(2)(pyrazole)] (7-9) have been prepared and their liquid-crystalline properties studied. Compounds 1 and 4 show monotropic smectic A phases, and complex 7 shows a monotropic nematic phase. The behavior of the melting points seems to be related to the X group directly bonded at the 3-position of the beta-diketonate ligand (1-6) or at the 4-position of the pyrazole ring (7-9). When X = OOC higher melting points are obtained. Two different polymorphs, red (M Ph) or blue (M = Ir) and yellow (M = Ph, Ir), have been obtained for complexes 1, 4, and 6. The yellow form for compound 4 (C31H35IrO9. CH3OH, monoclinic system, space group P2(1)/c (No. 14) with a = 26.991(6) Angstrom, b = 4.0093(8) Angstrom, c = 31.169(6) Angstrom, beta = 104.950(13)degrees, and Z = 4) has also been characterized by an X-ray single-crystal diffraction experiment in order to explain the influence of the packing arrangement in the formation of different polymorphs. Additionally, measurements of the first-order optical hyperpolarizability (beta) of the rhodium compounds and some of the precursor ligands using the EFISH technique have also been performed.

  γ-substituted β-diketone ligands with terminal metal Rh(I) have been prepared by reaction of the ligands with [Rh(CO)2(μ-Cl)]2. The mesomorphism of the ligands and complexes has been investigated using DSC and polarizing microscope. It is found that non-mesogenic ligands with n=7, 8, 9, 10, 11 can form liquid crystalline phase by direct coordination to metal. The effect of the terminal carbon number on the mesomorphism

  通过配体与[Rh（CO）2（μ- Cl）] 2的反应，制备了一系列新型的基于γ-取代的β-二酮配体与末端金属Rh（I）的有机金属配合物。配体和配合物的同构已使用DSC和偏光显微镜进行了研究。发现n＝7、8、9、10、11的非介晶配体可以通过与金属直接配位而形成液晶相。还讨论了末端碳原子数对同晶型的影响。
