Phosphate based new organic polymer networks for efficient dye sorption and catalyst loading for chemo-selective reactivity

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 POCl 3 with di- and tri-hydroxy organic linkers e.g. , quinol, 4,4′-biphenol, phloroglucinol and 1,3,5-(4-hydroxy...

Description
Summary: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 POCl 3 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. Phosphate-based porous organic polymers adsorb small cationic dyes efficiently and host gold nanoparticles for catalytic reduction of electron rich nitroaromatics.
