| titleOfInvention | 2,3-diphenyl-N, N'-bis (2-ethylhexyl) benzo [ghi] perylene diimide and the method of its preparation |
| abstract | The subject of the invention is 2,3-diphenyl-N, N'-bis (2-ethylhexyl) benzo [gh] perylenediimide represented by the formula 1 and a method for its preparation which consists in carrying out the process of cycloaddition of 1,2-diphenylacetylene into the cavity N, N'-bis (2-ethylhexyl) perylenediimide with simultaneous elimination of hydrogen, such that the overpressure-resistant reactor, preferably at least up to 5 atmospheres, is fed - in any order - N, N'-bis (2 -ethylhexyl) perylene diimide and 1,2-diphenylacetylene in molar proportions from 1: 2 to 1:50, the reactor is closed and a vacuum is created in it, i.e. a pressure of not more than 0.1 Pa, practically removing oxygen and other volatile substances, and then the reaction is carried out at a temperature from 260 to 310 ° C for a time not shorter than 24 hours, and after the cycloaddition reaction is completed, 2,3-diphenyl-N, N'-bis (2-ethylhexyl) benzo [ghi] perylene diimide is isolated in two ways, i.e. either a) the excess 1,2-diphenylacetylene is removed by vacuum sublimation in a known manner, and the product is isolated from the sublimation residue by chromatography on a silica gel column, first eluting the unreacted diphenylacetylene residues and some impurities with a low-boiling, saturated liquid hydrocarbon or a mixture of liquid saturated hydrocarbons, and finally the product, i.e. 2,3-diphenyl-N, N'-bis (2-ethylhexyl) benzo [gh] perylene diimide is eluted with dichloromethane, or: b) the excess 1,2-diphenylacetylene is removed by chromatography on silica gel, with a liquid, saturated hydrocarbon or a mixture of saturated liquid hydrocarbons, the final product, i.e. 2,3-diphenyl-N, N'-bis (2-ethylhexyl) benzo [gh] perylene diimide, is eluted with dichloromethane. The reaction product may be a phosphor, a nanografen or nanomaterials precursor for organic electronics, a component of active layers, for example in OLEDs, or a substrate for further cycloaddition or cyclo-dehydrocondensation. |
