Computational and experimental characterization of a fluorescent dye for detection of potassium ion concentration

The fluorescence of the SKC-513 ((E)-N-(9-(4-(1,4,7,10,13-pentaoxa-16-azacyclooctadecan-16-yl)phenyl)-6-(butyl(3-sulfopropyl)amino)-3H-xanthen-3-ylidene)-N-(3-sulfopropyl)butan-1-aminium) dye is shown experimentally to have high sensitivity to binding of

Polyadducts produced from nonlinear-optically active copolymers and polymerizable nonlinear-optically active monomers

The present invention relates to nonlinear-optically active copolymers which are composed of a chromophore acrylate, a glycidyl-functional acrylate, and a further acrylate unit, and to polyadducts produced from them by crosslinking with a carboxyl-functional polyester. The nonlinear-optical copolymers of the present invention, and the polyadducts prepared from them, possess an orientation stability in the crosslinked state, and a thermal stability, which makes them highly suitable for producing electrooptical and photonic components.

Process for preparing 3-(N,N-disubstituted amino)phenol

A process for preparing a 3-(N,N-disubstituted amino)phenol is herein disclosed which comprises reacting resorcin with a primary amine represented by formula (2): wherein R1 is an alkyl group, a cycloalkyl group, an alkenyl group, an alkoxyalkyl group, an aryl group or an aralkyl group, terminating the reaction when the conversion of resorcin is 50 mol % or more and when the amount of an N,N'-disubstituted-m-phenylenediamine as a by-product is 2 mol % or less of the amount of used resorcin, adding an alkyl halide represented by formula (3): wherein R2 is an alkyl group or a cycloalkyl group; and X is a halogen atom, to the obtained reaction mixture, adding an aqueous alkaline solution to the resultant reaction mixture to dissolve unreacted resorcin in the aqueous phase, extracting the 3-(N,N-disubstituted amino)phenol with an organic solvent, and then recovering unreacted resorcin from the aqueous phase. According to this process, the high-purity 3-(N,N-disubstituted amino)phenol can be prepared from resorcin in a substantially high yield, the production of by-products being inhibited.

Preparation of carbocylic M-aminohydroxyaromatics

A process for preparing carbocyclic m-aminohydroxyaromatics comprises reacting the corresponding o-- or m-halohydroxyaromatics or metal salts thereof with primary or secondary amines in the presence of a base and in the presence or absence of a diluent.

The autorecycling oxidation of benzylamine by synthetic 8-hydroxy-5-deazaflavin derivatives

Various 8-hydroxy-5-deazaflavin derivatives were synthesized as the model compounds of coenzyme F420. These compounds oxidized benzylamine to benzaldehyde more efficiently than the corresponding 8-unsubstituted 5-deazaflavin.
