Phosphate based organic polymer networks (OPNs) have been synthesized for the first time for dye sorption and heterogeneous catalysis. The OPNs were sythesized by the polycondensation of POCl₃ with di- and tri-hydroxy organic linkers e.g., quinol, 4,4′-biphenol, phloroglucinol and 1,3,5-(4-hydroxyphenyl)benzene. These show remarkably selective adsorption of cationic dyes methylene blue and propidium iodide via the electrostatic interaction of the polymers with the dyes. These OPNs also allow the in situ synthesis and stabilization of gold nanoparticles within the polymer networks which demonstrate effective heterogeneous, catalytic reduction of the aromatic nitro to amino group.

基于磷酸盐的新型有机聚合物网络可用于有效的染料吸附和催化剂负载以实现化学选择性反应

首次合成了基于磷酸盐的有机聚合物网络 (OPN)，用于染料吸附和多相催化。OPN 是通过 POCl ₃与二羟基和三羟基有机连接体（例如，醌醇、4,4'-联苯酚、间苯三酚和 1,3,5-(4-羟基苯基)苯）的缩聚反应合成的。这些表明通过聚合物与染料的静电相互作用对阳离子染料亚甲基蓝和碘化丙啶具有显着的选择性吸附。这些 OPN 还允许在聚合物网络中原位合成和稳定金纳米粒子，这证明了芳族硝基到氨基的有效多相催化还原。
