Abstract Ag, Au and Cu NPs have been encapsulated within as-synthesized 2D flexible porous coordination polymer {[Zn(TBIB)(HTCPB)]∙2DMF·H2O}n [TBIB = 1,3,5-tri(1H-benzo[d]imidazol-1-yl)benzene, H3TCPB = 1,3,5-Tris(4′-carboxyphenyl-)benzene] 1 at room temperature without employing any reducing agent. Presence of monodentate carboxylate along with the non-coordinated carboxylic acid groups (−COOH) are the main driving forces towards the synthesis of NPs from the polymer. Ag and Cu NPs synthesis takes place through acid formation (HNO3/HCl) while Au NPs have been synthesized by the redox activity of the polymer, elucidated by the electron paramagnetic resonance (EPR). Chemical and physical characteristics of the NPs have been provided by HRTEM. The coordination polymer not only synthesizes the NPs but also prevents them from agglomeration acting as a protective membrane to store fabricated NPs. Magnetic measurements show that all of the NPs integrated polymers reveal ferromagnetic properties at room temperature.
