2,5-di (3,4-dicarboxyphenoxy) - 4 '- phenylethynylbiphenyldianhydride (pephqda) / Qiyue custom supply porphyrin modified amphiphilic block copolymer peg113-pcl46-porphyrin

2,5- Two (3,4- Dicarboxyl phenoxy )-4'- Phenylethynyl biphenyl dianhydride (PEPHQDA)

2,5- Two (3,4- Dicarboxyl phenoxy ）-4'- The synthesis of phenylethynyl biphenyldianhydride can be divided into six steps ( Scheme 3.2), First ,2-(4- Bromophenyl ） Hydroquinone is esterified with acetic acid in pyridine to obtain 2,5- Diacetate -4- Bromobiphenyl (I),I With phenylacetylene Sonogashira Coupling reaction yields 2,5- Diacetate -4'- Phenylethynyl biphenyl (Ⅱ),II Under the alkaline condition of sodium hydroxide, the de esterification reaction takes place to produce 4- Phenylethynyl -2,5- Hydroquinone (III),IⅢI And 4- Nitrophthalonitrile is produced by nucleophilic substitution reaction 2,5- Two (3,4- Dinitrile phenoxy ）-4- Phenylethynyl biphenyl (IV), And then IV Hydrolysis under alkaline conditions produces tetra acids （(V), The target product is obtained by dehydration of the retaining ring with tetra acid 2,5- Two (3,4- Dicarboxyl phenoxy )-4 - Phenylethynyl biphenyl dianhydride ( VI).
