A series of novel organometallic complexes based on 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 ...
