Efficient mesoporous polymer based solid acid with superior catalytic activities towards transesterification to biodiesel

► Mesoporous polymeric solid acid was synthesized from sulfonation of PDVB. ► Novel PDVB based solid acid exhibit good hydrophobic and oleophilic feature. ► Oleophilic network results in samples with good miscibility for various substrates. ► PDVB based solid acids show good catalytic activities for production of biodiesel.
