Abstract
A novel class of luminescent microporous organic polymers (LMOPs) has been constructed by Heck coupling reactions of 1,3,5-tri(4-ethenylphenyl)benzene with aromatic halides. These polymers are microporous with the BET surface areas ranging from 391 to 791 m2 g−1 and possess quite narrow pore distributions at around 0.66 and 0.68 nm. The incorporation of 1,3,5-tri(4-ethenylphenyl)benzene into these polymers gives rise to the high luminescence, and the selection of aromatic halides could adjust the emissions from blue to green. The emissions of LMOPs could be quenched efficiently by picric acid, indicating that these polymers could be utilized as sensors for explosive detection.
