Metal Organic Frameworks(MOFs) are a compound of organic molecules and metal ions with regular structure and well-defined pores at the nano scale. They are crystalline materials with large internal surface areas and tunable chemical properties. Adsorption, separation and catalytic function of MOFs based on the size and shape of the pore and host-guest interactions are their functional application. In addition, MOFs have other applications such as bio/medicine, sensors and electronics which have attracted remarkable scientific interest in recent years. In this approach we have successfully encapsulated palladium nano particles in MOF and used it as catalyst in coupling reaction. This synthesis process could be achieved in one step through a simple temperature programming control without the addition of any external reducing agent.
