Preparing and application of a reactive mercury ion fluorescence probe

The invention discloses a reactive mercury ion fluorescent probe and a preparing method as well as application thereof. The method comprises the following steps: (1) 5-aminophenyl and 10, 15, 20- trisulfonate phenyl porphyrin (PNH2) is dissolved in distilled water to form solution of 7.5 mg / ml. The triphosgene is dissolved in dichloromethane to form solution of 5 MuL / mL. After the two is mixed at equal volume, react at room temperature for 3 to 5 hours and then purified, resulted to 5 -phenyl isothiocyanate base and 10, 15, 20 - trisulfate phenylporphyrin (PNCS); (2) 5 - phenyl isothiocyanate base and 10, 15, 20 - trisulfate phenylporphyrin (PNCS) and ethylenediamine derivatives are mixed in an equimolar ratio and dissolved in a mixed solvent of acetone and distilled water, to form a total concentration of 20 mg / mL solution. Finally, the solution reacts at room temperature for 6-10 hours, and after purification, the final product porphyrin-thiourea (PT) is obtained. The probe has good water solubility and shows high sensitivity and selectivity for mercury ions, and shows significant colors and fluorescence changes when detecting mercury ions. Combined with laser confocal scanning microtechnique, the probe can also be obtained the detecting imaging of the mercury ion within living cells.

Triblock polypropylene toughened and modified compatilizer as well as preparation method and application thereof

The invention discloses a triblock polypropylene toughened and modified compatilizer. The compatilizer is obtained by carrying out esterification reaction on the following raw materials in percentageby weight: 47.5-49.75% of carboxylic acid anhydride grafted polypropylene, 47.5-49.75% of carboxylic acid anhydride grafted and toughened elastomer and 0.5-5% of diamine derivative in a solvent, wherein the diamine derivative is an ethylenediamine or ethylenediamine derivative. The invention further discloses a preparation method and application of the riblock polypropylene toughened and modifiedcompatilizer. The toughened and modified compatilizer has the advantages that the compatibility between polypropylene resin and the corresponding elastomer is improved, and the performance of a polypropylene toughened elastomer material is improved.
