The invention provides synthesis of a binuclear liquid crystal polarized cyclometalated platinum complex by using 2,7-bi[4'-(4''-alkoxymethyl-2''-pyridine)-phenyl]-9,9-bi(dodecyl) fluorene as cyclomedtalating ligand and bi[(4-dodecoxy) benzoyl]methane as anionic ligand, and research of polarized fluorescence and liquid crystal performance thereof. In the method, alkoxymethyl is introduced to the 5-position of a pyridine ring of the traditional cyclomedtalating ligand 2-phenylpyridine molecule; a C N cyclomedtalating ligand of double alkoxy chain with dual coordination center and liquid crystal performance through fluorene bridge connection is constructed; a novel binuclear cyclometalated platinum complex is synthesized by using the bi[(4-dodecoxy) benzoyl]methane as the anionic ligand andthe 2,7-bi[4'-(4''-alkoxymethyl-2''-pyridine)-phenyl]-9,9-bi(dodecyl) fluorene liquid crystal material as the cyclomedtalating ligand. Compared with the traditional cyclometalated platinum luminescence material using the functional phenylpyridine as the cyclomedtalating ligand, the binuclear liquid crystal polarized cyclometalated platinum complex not only has high-efficiency luminescence performance, but also has good liquid crystal performance and polarized fluorescence performance. The binuclear liquid crystal polarized cyclometalated platinum complex of the invention provides a new way for obtaining the organic electrophosphorescent material with liquid crystal polarization.

The invention protects an illuminating device, comprising: a laser light source, used for emitting excitation light; a wavelength conversion device, arranged on the optical path of the excitation light, for absorbing at least part of the excitation light, and emitting the stimulated light and the untreated light Absorbed excitation light, the wavelength conversion device includes a light conversion element, the light conversion element is a single crystal or transparent ceramics, and the light conversion element includes an incident surface, an exit surface and a side surface; a diffuse mirror is arranged on the light On the optical axis of the conversion element, it is used to reflect the unabsorbed excitation light and expand its light divergence angle; the received light emitted by the wavelength conversion device combines with the excitation light emitted by the diffuse mirror to become the Emitting light from the lighting device. The illuminating device can provide illuminating light with high brightness and good safety performance. The invention also protects an automobile lighting fixture including the lighting device.
