摘要:A method of preparing a composition including crystalline particles of a halide perovskite, a composition and a perovskite-based device including the same. The halide perovskite has a chemical formula ABX3, wherein A is a monocation, B is selected from a combination of lead (II) and a dopant and X is selected from a halide.

标题 :Formamidine sulfate and phosphate salts, their production and their use in the synthesis of 1,3,5-triazine
发明人：GUETHNER THOMAS; KRAMMER DORIS; GRAML BERND
权利人:DEGUSSA
摘要:The invention relates to the use of formamidine salts of the general formula (I): (NH2-CH=NH2)nHx-nY, where Y is SO4, x is 2 and n is between 0.1 and 2.0, or Y is PO4, x is 3 and n is between 0.1 and 3.0. The salts obtained in accordance with the invention are especially easy to prepare from the technical perspective and make it possibly to produce high yields of highly pure 1,3,5-triazine by thermal decomposition of the corresponding formamidine salts.

摘要:The synthesis of new α-helix scaffolds mimicking i, i+3 or i+4, i+7 residues, was accomplished. The common pyridazine heterocycle originates from the easily available building block, 6. These scaffolds may be thought of as synthetic counterparts of amphiphilic α-helices having a “wet faceâ€? along one side and a hydrophobic face along the other side of the helix.
