摘要:A Series Of Amphiphilic Monochain Derivatives Of Stearic Acid,Ch3(Ch2)(16)Conh(Ch2)(N)Nh2 (N = 2,3,4,6),Ch3(Ch2)(16)Conh(Ch2)(2)S-2(Ch2)(2)Nh2,And [ch3(Ch2)(16)Conh](2)(Ch2)(2),Are Synthesized,And Their Self-Assembly Behaviors Have Been Investigated In 1,2-Dichloroethane (Dce). In Addition To The Concentration Of The Compound In Dce,The Number Of Methylene Units In Hydrophilic Segments Play A Crucial Role In Determining The Final Morphology Of Self-Assembling Structures From Nanotubules With 20 Nm Inner Diameter To Microspheres With An Average Diameter Of 20 Mu M. The External Texture Of The Microsphere Is Also Influenced By The Number Of Methylene Units In The Hydrophilic Segment. The Microspheres Formed By Highly Ordered Aggregattion Of Nanobelts Show High Thermal Stability. The Particular Processes And Causations Have Been Expatiated.

摘要:Disclosed in the present invention are a synthesis method and application of a benzoselenazole-1-ketone compound and a derivative thereof. Sulfoximine and the element selenium are used as raw materials, and by means of a rhodium catalysis direct C-H functionalization reaction, synthesis of a series of benzoselenazole-1-ketone compounds is achieved. The solution has the advantages of strong functional group compatibility, wide substrate universality, mild conditions, simple operations, and high efficiency and universality. Meanwhile, sulfoximine and the element selenium are used as initial raw materials, a direct C-H functionalization reaction is carried out, and by means of chiral phosphoric acid, synthesis of the chiral benzoselenazole-1-ketone compound is achieved. The application prospect is good, and a sulfydryl structure in biomacromolecules such as polypeptides, saccharides, drug molecules and proteins can be specifically marked. Good anti-SARS-CoV-2 virus activity is exhibited, a trastuzumab biological conjugate can effectively image HER 2 receptors on the cell surface, displays strong fluorescence, and can be applied to the preparation of an imaging reagent for the HER 2 receptor on the cell surface.

摘要:A method for preparation of graft modified ammonium polyphosphate with ultra-low hydroplaning and resistance to hydrolysis belongs to the field of the preparation of flame retardant. Ammonia water is used as hydrolytic agent of amino silane. In the early stage of synthesis of ammonium polyphosphate with phosphorus pentoxide, diammonium hydrogen phosphate and melamine as raw materials, hydrolyzed amino silane ammonia mixture is added, and continues warming reaction, when the temperature drops to a certain temperature, melamine is added to maintain high temperature reaction for a certain period of time, then cools to obtain graft modified ammonium polyphosphate with ultra-low hydroplaning and resistance to hydrolysis. The present disclosure grafts ammonium polyphosphate with two kinds of amino grafting in stages, and the modified ammonium polyphosphate products after grafted basically have no hydroplaning when meets water. Because of addition of excessive melamine in late stage, the excessive melamine is not only used for graft modified ammonium polyphosphate, but also used for reacting with acidic ammonium polyphosphate whose polymerization is incomplete, making it form polyphosphate melamine, eliminate the formation of water-soluble small molecules, and reduce water solubility of the products to a greater extent.
