A wide set of conjugated microporous polymers (CMPs) are synthesized via a facile Pd‐catalyzed Suzuki‐Miyaura coupling reaction between organo‐boron reagents and organic halides in the presence of K2CO3. According to multiple characterizations, the resulting polymers are thermally stable and fluorescent with large specific surface areas (SSAs) and narrow pore distributions. Especially, polymer synthetized by using 1,3,6,8‐tetrabromopyrene (TBP) and 1,4‐phenylenediboronic acid (PDBA) exhibits the largest apparent SSA up to 1071 m2 g−1, H2 uptake capacity of 152.77 cm3 g−1 (77 K, 1 bar) and CO2 uptake capacity of 58.97 cm3 g−1 (273 K, 1 bar). Furthermore, parallel experiments prove TBP and PDBA are the best building blocks for these series polymers synthesis. Moreover, CMPs feature large SSAs, outstanding thermal and fluorescent performances, and facile preparation, making themselves promising candidates for the future industrial applications.

Suzuki-Miyaura偶联反应一锅轻松合成多功能共轭微孔聚合物

在K 2 CO 3存在下,有机硼试剂与有机卤化物之间通过Pd催化的Suzuki-Miyaura偶联反应,可以合成大量共轭微孔聚合物(CMP)。根据多个特征,所得聚合物是热稳定的并且具有大的比表面积(SSA)和狭窄的孔分布的荧光。尤其是,使用1,3,6,8-四溴re(TBP)和1,4-苯二硼酸(PDBA)合成的聚合物表现出最大的表观SSA值,最大为1071 m 2  g -1,H 2吸收容量为152.77 cm 3  g -1(77 K,1巴)和CO 2吸收能力为58.97 cm 3  g -1(273 K,1 bar)。此外,平行实验证明,TBP和PDBA是这些系列聚合物合成的最佳构件。此外,CMP具有大型SSA,出色的热和荧光性能以及易于制备的特性,使其成为未来工业应用的有希望的候选者。
