标题:Dynamic covalent chemistry of spiropyrans for synthesis of photoswitchable photoinitiators and uses thereof
发明人：GARMSHAUSEN YVES
权利人:XOLO GMBH
摘要:The present invention relates to spiropyrans and process for the manufacture of them. In particular, a method is provided to exchange the indole and salicylaldehyde part of a spiropyran in a reversible reaction. The method is used for the synthesis of dual color photoinitiators with specific substituents and substitution patterns, which result in improved dual color volumetric printing (xolography). Furthermore, a process for locally polymerizing a starting material by dual color photopolymerization is disclosed.

摘要:The present invention provides the methods of synthesis of [5]helicene compounds and the use of the said compounds conjugating with biomolecules to work as molecular reporter for diagnostic. The compounds in the present invention have the chemical structure illustrated in the formula (1): wherein G is a connecting group composes of 2 carbon atoms selected from the group consisting of ethane and ethylene; A is a separated or connected group selected from the group consisting of cyano and imide; D1 is selected from the group consisting of oxyalkanoic acid, oxyalkanal and oxyalkanesulfonate; and D2 has structure selected from the group consisting of hydroxyl, oxyalkanoic acid, oxyalkanal, alkyl oxyalkanoate, oxyalkanol and oxyalkanesulfonate. The compounds in the present invention compose of aromatic [5]helicene core comprising long it-conjugating system. The said compounds contain functional groups which able to link with biomolecules and they are soluble in water or other solvents that used in binding process with biomolecules. Moreover, owing to having proper chemical structure, the compounds in the present invention exhibit good fluorescent emission in wavelength of 425-675 nm. When the said compounds connected with biomolecules, the biomolecules give good fluorescence and can be detected under ultraviolet radiation.

标题:Preparation method and application of zero-valent aluminum/iron-bearing clay composite for catalyzing persulfate to oxidize organics
发明人：YANG HU; YANG RAN
权利人:NANJING UNIVERSITY OF TECHNOLOGY
摘要:A preparation method and application of a zero-valent aluminum/iron-bearing clay composite for catalyzing a persulfate to oxidize organics are provided, which belongs to the field of water environmental treatment. A novel catalyst is prepared by an iron-bearing clay and a zero-valent aluminum through a simple ball milling method, for achieving the effect of activating a persulfate to efficiently oxidize and degrade refractory organics in water. The preparation method and operation process thereof are simple. Compared with a chemical synthesis method, the method of the present disclosure brings about less secondary pollution, and has a shorter synthesis time, higher yield and lower cost. The modified material is the natural iron-bearing clay, which is widely available, non-toxic and stable as a heterogeneous catalyst.
