Application | 2, 5-diamino-1, 4-benzodithiophene dihydrochloride can be used as an organic solvent, it is also useful as an intermediate in organic synthesis. Examples of its application are as follows: 1) preparing an electrical memory device based on one-dimensional organic-inorganic hybrid polymer chain, adding divalent metal salt aqueous solution Dropwise to oxygen-removing 2, in the organic solution of 5-diamino-1, 4-benzenedithiophene dihydrochloride, the pH value of the system is adjusted to 7, and then the system is stirred and reacted at room temperature for 6 hours to prepare an organic-inorganic hybrid polymer; organic-inorganic hybrid polymer is dissolved in organic solvent to prepare organic-inorganic hybrid polymer saturated solution; Organic-inorganic hybrid polymer solution is coated on the substrate to prepare organic film layer; Then the electrode is prepared on the organic film layer, the electrical memory device based on one-dimensional organic-inorganic hybrid polymer chain is obtained, which has good high temperature stability, and the organic electrical memory device with sandwich structure is prepared, and the ternary organic electrical storage behavior is successfully realized, moreover, the device has a low turn-on voltage and a simple preparation process, and the ternary yield of the electrical memory device is successfully improved by changing the central metal ion. 2) in a gas-filled glove box, To a 100ml round bottom Schlenk flask fitted with a magnetic stir bar was added 172mg of SnCl 2 dihydrate, 4.00g of 2, 5-diamino-1, 4-benzenedithiophene dihydrochloride, 4.32G of p-aminobenzoic acid, and 27.1 of methanesulfonic acid. The addition of methanesulfonic acid results in degassing of HCl, which is captured by a sodium carbonate bath. The flask was purged with nitrogen and then placed in a hot oil bath at a temperature of 75 °c. The oil bath temperature was maintained at 75 °c until the evolution of HCl gas subsided. The oil bath temperature was then raised to 165 °c and the duration of the reaction was maintained at this temperature. As the oil bath temperature increases, a nitrogen flow (2.5L/ min) is passed through the reaction solution, which will be maintained during the reaction. The reaction was allowed to proceed for 10 hours before the heating was removed and allowed to cool. Water was added to the cooled reaction, and 4,4 ' - [1,3] thiazolo [4,5-f] [1,3] benzothiazol-2 was added, 6-diyldiphenylamine with some reaction intermediates and impurities (8.439G solid when water is dried). The crude solid was isolated by filtration, resuspended in water and the solution brought to pH 7 by addition of concentrated ammonium hydroxide. The solids were again collected by filtration and they were 4,4' - [1,3] thiazolo [4,5-f] [1,3] benzothiazol-2, A mixture of 6-diyldiphenylamine with some reaction intermediates and impurities. By crystallizing the above neutralized solid in N-methylpyrrolidone, pure 4,4 ' - [1,3] thiazolo [4,5-f] [1,3] benzothiazole-2, 6-diphenylamine. |
