Arylamine-Linked 2D Covalent Organic Frameworks for Efficient Pseudocapacitive Energy Storage

The development of new linkages is one of the most efficient strategies to enrich the diversity of covalent organic frameworks (COFs). Particularly, functional linkages can endow COFs with additional tailored properties besides the building units, which further diversify COFs with desirable functions. Herein, we have developed a new arylamine linkage for the construction of COFs. Two new arylamine-linked COFs (AAm-TPB and AAm-Py) were prepared by condensing cost-effective dimethyl succinyl succinate (DMSS) with corresponding multitopic amines (TPB-NH2 and Py-NH2). Due to the abundant electroactive diphenylamine moieties in the COF skeletons resembling that of polyaniline (PANI), a state-of-the-art conductive polymer, the pseudocapacitive energy storage performance of AAm-TPB was further investigated. Remarkably, the AAm-TPB electrode exhibits a high capacitance of 271 F g?1 with a three-electrode setup at a discharge rate of 1 A g?1, which represents one of the highest capacitances among the reported COF-based electrode materials.

PROCESS FOR THE PREPARATION OF ORGANIC PIGMENTS

The present invention relates to advantageous processes for the manufacture of organic pigments and their precursors. The invention particularly relates to reactions carried out in an "All In One Reactor" (Draiswerke GmbH, Germany), a kneader like the TurbuKneader of the same company, a paddle dryer like the Turbudry of the same company or a related system and thereby submitting the reaction mixtures to enhanced driving power as expressed by a Froude number>1, the reaction mixture being caused to react in high concentrations at elevated temperature.

Process for the production of 2,5-di(arylamino)-3,6-dihydroterephthalic acid dialkyl ester, and process for the production of quinacridone from said ester as intermediate

A process for producing 2,5-di(arylamino)-3,6-dihydroterephthalic acid dialkyl ester having a high purity from 1,4-cyclohexanedione-2,5-di(carboxylic acid alkyl ester) at high yields for a short period of time; a process for producing quinacridone of which the byproduct content is small, from the above 2,5-di(arylamino)-3,6-dihydroterephthalic acid dialkyl ester; and a process for producing quinacridone of which the particle diameter is adjusted as desired, from the above 2,5-di(arylamino)-3,6-dihydroterephthalic acid dialkyl ester without adding a step of forming a pigment.
