Abstract:
PURPOSE: A cycloalkane dicarboxamide compound is provided to improve mechanical strength and heat resistance when used as a hardener of polyester powder resin. CONSTITUTION: A cycloalkane dicarboxamide compound is represented by formula 1. In formula 1, R1~R4 are independently linear or branched C1-C7 alkyl groups of which one or more hydroxyl groups are substituted; R9 and R10 are independently hydrogen, hydroxyl group, or hydroxyl-substituted or non-substituted C1-C7 alkyl groups; and m and n are independently integers between 1 and 3.

PURPOSE: A 2-[2-styryl pyridine-4(1H)-ylidene]malononitrile derivative of which fluorescence characteristic changes is provided to use in composition for an optical sensor and the optical sensor. CONSTITUTION: A 2-[2-styryl pyridine-4(1H)-ylidene]malononitrile derivative is denoted by chemical formula 1. The 2-[2-styryl pyridine-4(1H)-ylidene]malononitrile derivative is prepared by condensing benzaldehyde derivative of chemical formula 4 with 2-[2-methylpyridine-4(1H)-ylidene]malononitrile derivative. A 2-[2-methylpyridine-4(1H)-ylidene]malononitrile derivative of chemical formula 2 is prepared by reacting a primary amine derivative of chemical formula 5 with 2-[2-methyl-4H-pyrane-4-ylidene]malononitrile derivative of chemical formula 4. A composition for sensing pH concentration contains 2-[2-styrylpyridine-4(1H)-ylidene]malononitrile derivative as a fluorescent dye.
