Four truxene-based conjugated microporous polymers (Tr-CMPs) were prepared via different synthetic methods and their structure-property relationships were studied.The polymer networks have high Brunauer-Emmett-Teller (BET) specific surface areas ranging from 554 m2.g-1 to 1024 m2.g-1.Pore sizes of the CMPs with different linkers are mainly located between 0.60 and 1.96 nm.Among all the Tr-CMPs,TrCMP4 has the highest BET surface area of 1024 m2.g-1 and exhibits the highest H2 uptake of 0.88 wt%.Tr-CMP2 prepared by Suzuki-Miyaura coupling reaction has the highest photoluminescence quantum yields (PLQYs) of 13.06% and CO2 uptake of 6.25 wt%.
