Fabrication of an Electrochemical Sensor Based on a New Nano-ion Imprinted Polymer for Highly Selective and Sensitive Determination of Molybdate

In this work a new chemically modified carbon paste electrode was constructed for accurate, simple, sensitive and selective determination of molybdenum (VI) ions. The results of modified electrode by an ion imprinted polymer were compared with those obtained with carbon paste electrode. The results showed the stripping peak currents had a dramatic increase at the modified electrode. Under the o...

In situ production of silver nanoparticles on an aldehyde-equipped conjugated porous polymer and subsequent heterogeneous reduction of aromatic nitro groups at room temperature.

In a metal-free procedure, chelating thiol groups and an electrophile react to assemble a robust, conjugated porous polymer with pendant aldehyde functionalities. These groups are able to reduce Ag(i) ions to generate, in situ, Ag(0) nanoparticles evenly dispersed in the polymer matrix. The Ag(0)-polymer composite enables selective reduction of aromatic nitro compounds as a heterogeneous cataly...

Poly(P-N-Chlorostyrenesulphonamide): A New and Efficient Chlorinating Agent for Aromatic Rings

Poly(p-N-chlorostyrenesulphonamide) synthesized via direct chlorination of poly[(p-styrene) sulphonamide], can be used for selective chlorination of aromatic compounds. Aromatic rings of the anisole, p-xylene, ethylbenzene and toluene are chlorinated with good yields. The polymer can be recovery, rechlorinated and reused several times.

Imidazole Functionalized Magnetic Fe3O4 Nanoparticles a Highly Efficient and Reusable Brønsted Acid Catalyst for the Regioselective Thiocyanation of Aromatic and Heteroaromatic Compounds at Room Temperature in Water:Ethanol

The Magnetically recoverable Fe3O4 nanoparticle and the supported brønsted acidic ionic liquid 1-methyl-3-(3-trimethoxysilylpropyl) imidazolium hydrogen sulfate (Fe3O4-IL-HSO4) were synthesized and used as efficient magnetic catalysts for the regioselective thiocyanation of aromatic and heteroaromatic compounds at room temperature in Water: Ethanol. This procedure provided the target thiocyanat...
