Abstract

The oligomerization of light olefins, such as isopentene, is crucial for producing valuable products like industrial chemicals in the petrochemical industry; however, developing efficient and stable catalysts remains challenging. In this study, we synthesized a sulfonated porous organic polymer, HSO₃-POP-TB, via Friedel-Crafts alkylation using 1, 3, 5-triphenylbenzene (TB) and 4, 4’-dichloromethylbiphenyl (BB), followed by chlorosulfonic acid (HSO₃Cl) sulfonation. The strong acidity and unique micro-/mesoporous structure of HSO₃-POP-TB are key to achieving high isopentene conversion and excellent dimer selectivity. Optimized HSO₃-POP-TB demonstrated exceptional catalytic performance, with an isopentene conversion rate of 81.7 % and 95.0 % selectivity for the dimer product at 70 °C, surpassing conventional solid acid catalysts. Additionally, HSO₃-POP-TB exhibited remarkable thermal stability and acid resistance, maintaining high activity over five reaction cycles without significant efficiency loss. These results highlight the potential of HSO₃-POP-TB as a promising catalyst for the efficient and sustainable conversion of light olefins into valuable chemicals, addressing economic and environmental concerns.
