Homogeneous transition metal catalysts are many obvious advantages to controlling reaction speed and selectivity under relatively mild operating conditions. However, homogeneous catalysts are difficult to separate from the products and reuse in industry. Because of that, heterogeneous catalysts receive much attention in industrial processes, but they often have some shortcomings in low selectivity, low activity, and tough operating conditions. One of the ways to solve these problems is anchoring of transition metal complexes to inorganic supports. The heterogenization of homogeneous molecular catalysts enhances their stability and reaction scope while maintaining their tunability and activity-selectivity. Herein, we utilize metal-organic frameworks (MOFs) as a heterogeneous support for incorporating transition metal catalysts. Well-designed MOFs are suitable for catalyst due to their high surface areas and porosity. [NiL_CN]₂(BPTC) has a large pore channel anchoring the transition metal (Cu, Co, Pd, Mn, Ni and Cr), it is used to catalysts for ethylene oligomerization. Linear α-olefins will be synthesized through the ethylene oligomerization, which can be used as intermediates for manufacturing of detergents and lubricants. We expect that transition metal included with [NiL_CN]₂(BPTC) is a highly active catalyst for ethylene oligomerization.
