The present invention belongs to the field of preparation and application of
metal materials and relates to a class of Cl / Br
halogen-doped ionic
antimony complexes and their preparation methods and applications. The general
structural formula of the complex is shown below: #imgabs0#, wherein R is methyl, ethyl, n-propyl or n-butyl; and x=0, 1, 2, 3, 4 or 5. The preparation method comprises the following steps: adding a
benzylamine salt and
antimony trichloride or
antimony tribromide to a
solvent in a
molar ratio, reacting the mixture, and using
ether as a reverse
solvent to obtain a
single crystal of the target product; or adding a
benzylamine salt and
antimony trichloride or antimony
tribromide to a
solvent in a
molar ratio, and heating the mixture to obtain a
single crystal of the target product. The
luminescence properties of the material can be controlled by varying the
halogen type or organic cation in the complex. Due to the advantages of the antimony complex, such as high stability, simple preparation, and high-efficiency, short-life
luminescence, the ionic antimony complex has a wide range of uses and can be applied to fields such as X-
ray imaging and lighting displays.
