Abstract:
The present invention is to provide a colored composition having higher heat resistance compared with conventional colored compositions. The present invention further relates to: “a polymer having a monomer unit derived from a monomer which has (i) a cationic rhodamine derivative having, as an counter anion, an anion including an aryl group having an electron-withdrawing substituent and an anion group and (ii) an ethylenically unsaturated bond”, “a monomer which has (i) a cationic rhodamine derivative having, as an counter anion, an anion including an aryl group having an electron-withdrawing substituent and an anion group and (ii) an ethylenically unsaturated bond”, “a colored composition comprising the above-described polymer or the monomer”, and “a colored composition for a color filter comprising the above-described polymer or the monomer”.
Abstract:

Abstract:
The present invention provides a titanium ligand-modified black phosphorus and the preparation method and use thereof. The titanium ligand-modified black phosphorus is a complex of black phosphorus and a titanium ligand having a structure represented by formula (I): wherein in the formula (I), R1 comprises C1-C6 alkyl, or phenyl optionally further substituted with 0 to 5 groups each independently selected from halogen atom, C1-C6 alkyl, nitro, hydroxy, amino or C1-C3 alkoxy; the C1-C6 alkyl or C1-C3 alkoxy is optionally further substituted with 0 to 3 groups each independently selected from halogen atom, nitro, hydroxy, amino, methyl, ethyl or n-propyl. The titanium ligand-modified black phosphorus of the present invention is not likely oxidized without changing inherent properties of the black phosphorus, and the antioxidant capacity is greatly enhanced.
Abstract:
Provided are ionic thermal acid generators comprising an anion of an aromatic sulfonic acid comprising one or more fluorinated alcohol group and a cation. Also provided are photoresist pattern trimming compositions that include an ionic thermal acid generator, a matrix polymer and a solvent, and methods of trimming a photoresist pattern using the trimming compositions. The thermal acid generators, compositions and methods find particular applicability in the manufacture of semiconductor devices.
Abstract:
Provided is a stilbazolium derivative represented by the general formula (I): wherein R1, R2, R3, and R4 independently represent hydrogen, halogen, alkyl, hydroxyl, carboxyl, or amino; R5 represents hydrogen or alkyl; X represents oxygen or NR6 (R6 is hydrogen or alkyl); and Y− represents an anion. In the general formula (I), some or all of hydrogens maybe deuterium.
Abstract:
The present invention provides a process for the preparation of agomelatine and its intermediate compounds. The invention also provides an intermediate compound of agomelatine represented by Formula (V).
Abstract:
It is intended to provide a method for immobilizing, onto a column carrier, a compound having a sulfo group or a compound to which a sulfo group can be added. The method comprises immobilizing the compound onto the column carrier using a linker comprising: a sulfo group-binding group capable of forming a bond with the sulfo group in the compound; and a carrier-binding group capable of forming a bond with a group present on the surface of the column carrier.
