聚乙二醇二取代的血卟啉(HP -diPEG)的制備方法

通過(guò)酯基水解得到聚乙二醇二取代血卟啉衍生物,，制備方法如下： 

步驟一：將HP-tPEG和KOH的甲醇溶液(質(zhì)量比20: 100,30 mL)加入到單口燒瓶(100 mL)中,80 C回流反應(yīng)24 h后,反應(yīng)體系恢復(fù)到室溫,  

步驟二：將其置于透析袋(截留分子量1X10*),在5 L水中透析24 h,每隔4 h換-次去離子水。  

步驟三：冷凍干燥得到HP -diPEG(0. 399 g,產(chǎn)率35%)  合成路線如圖1所示,。

高分子化學(xué)是一類(lèi)以聚合物為基礎(chǔ)的產(chǎn)品,，西安齊岳生物可以提供的高分子材料豐富,，特點(diǎn)在于可以提供定制類(lèi)和復(fù)雜的聚合物產(chǎn)品,，我們的普通聚合物主要聚乙二醇、生物可降解共聚物,，星型或者樹(shù)枝聚合物,，聚氨基酸以及PH響應(yīng)或者ROS響應(yīng)或GSH響應(yīng)的聚合物
