[0032] 1 Preparation of PDI-OH self-assembled film and ZnS / PDI-OH hybrid film

[0033] (1) PDI-OH self-assembled membrane: 5.0 ml containing PDI-OH ( figure 1 ) in dichloromethane (0.20 mg mL -1 ), added to the Petri dish (diameter: 90 mm, height: 1.8 cm), and then 50 mL of water was slowly added to the surface of the dichloromethane solution. (Note: The amount of water added cannot make the air / CH 2 Cl 2 The interface is completely covered, leaving a small hole for CH 2 Cl 2 The solvent can evaporate along the way). During the solvent evaporation process, the PDI-OH molecule will gradually be in the CH 2 Cl 2 - Self-assembly at the interface of water to form excellent nanostructures. Wait for CH 2 Cl 2 The volatilization is complete, and the densely packed film will remain on the water surface ( figure 2 ). Then, with 300 mesh copper mesh, quartz sheet and Si / SiO 2 The substrate is taken out by horizontal pulling method. During the transfer process and after the...

During the transfer process and after the transfer process is completed, there will be water droplets remaining on the copper grid or substrate, which can be dried naturally. It can be repeated 15 times to prepare 15 l...

Abstract

According to the invention, two novel-structured amphiphilic perylene bisimide derivatives (PDI-OH and PDI-2OH) are used for the first time to be prepared into a self-assembled film in a ZnSO4 subphase solution, then the self-assembled film is soaked into a saturated sulfuretted hydrogen solution for different times, and the ZnS / PDI mixed particles with different crystalline phases and the particle sizes of 5, 10, 15 and 20 nanometers are successfully prepared. Besides, various modern means are taken to perform complete and meticulous characterization tests on the structure, appearance and semiconductor property of the particles. The method is simple in operation, the reaction process is easy to control, the process is performed at room temperature in the aqueous phase, the preparation condition is mild, the cost is low, and the process is easy to realize.

Description

technical field [0001] The invention relates to a method for preparing zinc sulfide / amphiphileimide hybrid materials with different crystal phases, which has low preparation cost, simple operation and high application value, and can control the size and crystal phase of zinc sulfide in the hybrid materials , forming an inorganic / organic hybrid material with excellent semiconductor properties, belonging to the technical field of semiconductor materials. Background technique [0002] The low-cost method for assembling organic-inorganic hybrid nanomaterials has attracted extensive attention from scientists in different fields. Hybrid nanomaterials often exhibit unique optoelectronic properties not possessed by single systems, however, these properties strongly depend on the size and crystal form of the nanomaterials. Therefore, controlled synthesis of organic-inorganic hybrid nanomaterials with a certain size and crystal form is expected. In the method of preparing hybrid nan...
