▎ 摘　　要

NOVELTY - The device has multiple inner tubes (1) that are connected in sequence. A mesh screen is set between two adjacent inner tubes. The mesh screen is provided with the functions of rectification trays, adsorption of impurities, ventilation and heat conduction. The mesh screen is provided with a support and an adsorbent on the support. The support is provided with a hollow or mesh structure. The adsorbent is provided with one or more of activated carbon, carbon nanotube, graphene, carbon fiber, silica gel, diatomaceous earth, porous ceramics and magnetic metal particles. USE - Sublimation and purification device for organic semiconductor materials. ADVANTAGE - The mesh screen has good thermal conductivity and high thermal stability. The density of the ventilation pores is adjusted to prevent the precipitation of purified substances and facilitate subsequent cleaning of impurities. The adsorbed substances are fixed on the mesh can further adsorb impurities and purifies products. The adsorbents are replaced according to the nature of the purified components to achieve better purification results. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for sublimation purification method using the sublimation purification device for organic semiconductor materials. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the sublimation and purification device for organic semiconductor materials. Inner tube (1) Adsorbent film (2) Crude material (5)
