A new type of metal coordinated liquid crystalline polymers has been synthesized by complexation of metal ions with β-diketone based side chain liquid crystal polysiloxane (DKLCP).The complexation of copper ions with DKLCP greatly increases the phase transition temperature Tk from crystalline state to liquid crystalline state and Tcl from LC to isotropic state and makes the range of phase transition △T(△T= Tcl- Tk ) widened. These complexes are soluble in common organic solvents. However, the incorporation of europium ions into DKLCP molecules gives rise to reduction in liquid crystallinity and crosslinking in some cases. The DKLCP coordinated with suitable amount of Eu ions can show good liquid crystallinity and fluorescent property.
