Characterization of Microcapsules Prepared by Interfacial Polycondensation of Methylene Bis(phenyl isocyanate) with Hexamethylene Diamine
Polyurea microcapsules containing 2-chloro-N-(2,6-diethylphenyl)-N-(methoxymethyl)acetamide as the active agent were prepared by the method of interfacial polycondensation with methylene bis(phenyl isocyanate) as the multifunctional isocyanate, hexamethylene diamine as the diamine, and anionic sodium lignin sulphonate as the emulsifying agent . Thermal stability of the microcapsules was investi...
متن کاملPoly(p-phenylene Vinylene) Nanoparticles by Acyclic Diene Metathesis (admet) Polycondensation in Aqueous Emulsion
Chair of Chemical Materials Science, Department of Chemistry, University of Konstanz, Germany Introduction Poly(p-phenylene vinylene) (PPV) and its derivatives are amongst the most widely studied class of conjugated polymers since the discovery of their electroluminescent properties in 1990. These polymers are studied for applications in numerous photonic devices such as organic solar cells, or...
متن کاملSynthesis and antiprotozoal activity of oligomethylene- and p-phenylene-bis(methylene)-linked bis(+)-huprines.
We have synthesized a series of dimers of (+)-(7R,11R)-huprine Y and evaluated their activity against Trypanosoma brucei, Plasmodium falciparum, rat myoblast L6 cells and human acetylcholinesterase (hAChE), and their brain permeability. Most dimers have more potent and selective trypanocidal activity than huprine Y and are brain permeable, but they are devoid of antimalarial activity and remain...
متن کاملThiocyanate Ion Selective Solid Contact Electrode Based on Mn Complex of N,N'-BIs-(4-Phenylazosalicylidene)-O-Phenylene Diamine Ionophore
A thiocyanate ion selective poly(aniline) solid contact electrode based on manganese complex of N,N’-bis-(4-phenylazosalicylidene)-o-phenylene diamine ionophore was successfully developed. The electrode exhibits a good linear response of 58.1 mV/decade (at 20 ̊C ± 0.2 ̊C, r = 0.998) with in the concentration range of 1 × 10 ~ 1 × 10 M thiocyanate solution. The composition of this electrode was: i...
متن کاملSynthesis of 2,2′-(1,4-Phenylene)bis-3,4-dihydro-2H-1,3-thiazin-4-ones and their Facile Recyclization to 2,2′-(1,4-Phenylene)bis(pyrimidin-4-one) and/or 2,2′-(1,4-Phenylene)-bis-(thieno[2,3-d]pyrimidin-4(1H)-one) Derivatives
1,3-Thiazines are an important type of heterocycles showing a wide variety of pharmacological properties. Thus, 1,3-thiazine derivatives have recently been reported as cholecystokinin antagonists [1], antimycobacterial agents [2], cannabinoid receptor agonists [3], and inhibitors of NO synthase (NOS) [4], as antibacterial [5], antipyretic [6], anti-inflammatory [6, 7], analgesic [7], antitumor ...
