Abstract
A series of conjugated microporous polymers (CMPs) based on bromophenol blue (BB) and bromocresol green (BG) have been synthesized via Sonogashira-Hagihara cross coupling reaction with surface areas up to 747 m2/g. The CMPs can be post functionalized with chlorosulfonic acid to yield corresponding sulfonated polymers with high acidity up to 7.67 mmol/g. The sulfonated CMPs showed excellent catalytic activity for the esterification of free fatty acids and transesterification of various vegetable oils and waste cooking oil as well as excellent reusability up to 4 consecutive runs without significant activity loss. These sulfonated CMPs have potential applications as recyclable acid catalysts for environmentally friendly biodiesel production from waste cooking oil.
