Abstract Three isomers (nongeminal cis -2,4,6 ( 2 ); nongeminal trans -2,4,6 ( 3 ); geminal 2,2,4 ( 4 )) were isolated from the reaction of hexachlorocyclotriphosphazatriene (trimer) ( 1 ) with diethylene glycol monobutyl ether (DEGBE). The substitution reactions of cis -tris isomer ( 2 ) with 3-amino-1-propanol were investigated under different solutions conditions to provide amphiphilic phosphazene
摘要从六氯环三磷杂氮杂三烯(三聚体)的反应中分离出三个异构体(非geminal顺式-2,4,6(2); nongeminal反式-2,4,6(3);双键的2,2,4(4))(1 )与二甘醇单丁醚(DEGBE)。研究了在不同溶液条件下,顺式-tris异构体(2)与3-氨基-1-丙醇的取代反应,以提供两亲性磷腈(5)。所有化合物均使用元素分析,31 P NMR和质谱进行了表征。研究了化合物5的热敏性质。化合物5可溶于水和有机介质。这表明化合物5是两亲性分子。在水中测得浓度依赖性的LCST(较低的临界溶液温度)为5。化合物5在水性介质中表现出可逆的和热敏的相变,从可溶状态转变为不溶状态。化合物5在接近体温的37℃(浓度为7重量%)下显示LCST。

reactions of non-geminal cis-2,4,6 diethylene glycol monobutyl ether substituted cyclotriphosphazene (2a) with ethylamine, hexylamine and dodecylamine. Compounds 3–5 were characterized by 31P NMR, MS and elemental analysis. The thermosensitive properties of compounds 3–5 were investigated. Compound 3 showed thermosensitive properties which might enable it to be used as a biomedical material.
摘要由非双键的顺式2,4,6二甘醇单丁基醚取代的环三磷腈(2a)与乙胺,己胺和十二烷基胺反应合成了三种新型化合物(3-5)。通过31 P NMR,MS和元素分析对化合物3-5进行了表征。研究了化合物3-5的热敏特性。化合物3表现出热敏性质,这可能使其能够用作生物医学材料。
