Description
Summary:Pyrylium salts are a type of representative and convincing example of versatility and variety not only as a nodal point in organic transformations but also as an attractive building block in functional organic materials.Herein,we report an effective synthetic protocol to fabricate a new pyrylium-containing porous organic polymers(POPs),named TMP-P,via Knoevenagel condensation with 2,4,6-trimethylpyrylium salt(TMP)as the key building block and 1,4-phthalaldehyde as the linker.The resulting ionic polymer TMP-P exhibited efficient visible-light-driven heterogeneous photodegradation of Rhodamine B,owing to the presence of wide visible light absorption and a narrow optical band gap triggered pyrylium core in the framework.
