Abstract

The invention discloses a preparation method for a chalcogenide semiconductor/carboxylation PPV (polyphenylene vinylene) electroluminescence composite material. The electroluminescence composite material is prepared by means of complexation between semiconductor metal salt and carboxylation PPV firstly and then by means of hydrothermal reaction, the semiconductor metal salt is selected from soluble nitrate or halide of Zn, Cd, Pb or Bi, and the carboxylation PPV refers to poly[2-methoxy-5-(5'-carboxypentyloxy) p-phenyl acetylene]. The carboxylation PPV serving as an organic phase to be doped and composited with an inorganic semiconductor, and the carboxylation PPV is connected with the inorganic semiconductor by means of coordination bonds, so that inorganic particles are uniformly dispersed, the two phases form a uniform system, energy and charge transfer on the two phase interfaces is improved, the composite material has processibility of polymer and photoelectric property of semiconductor materials, and the novel electroluminescence material high in stability and luminous efficiency is provided for the fields such as large-area flexible display and solid-state luminescence and the like.

Description

1. Technical field

[0001] The invention relates to the preparation of a novel electroluminescence material, specifically, a preparation method of a compound material of a chalcogen semiconductor and a carboxylated PPV derivative. 2. Background technology

[0002] Conjugated polymers not only have the optoelectronic properties of semiconductors, but also have good processability and mechanical properties. They are excellent light-emitting materials, but their low carrier mobility limits their applications. Poly(p-phenylene vinylene) is the earliest conjugated polymer used in the field of electroluminescence. Due to its excellent photoelectric properties, it has been extensively researched and developed, but its poor stability and low luminous efficiency limit it. Applications. Inorganic semiconductors such as PbS, CdS, BiS, and ZnS have high electron mobility, unique optical, electrical, magnetic properties and geometric structures, and have become research hotspots. However...
