摘要：

Two hypercrosslinked microporous carbazole-based polymers (namely C-POP-1 and C-POP-2) were prepared through an efficient Friedel - Crafts coupling approach. Both samples have different porous structures via regulating the length of two-node linear organic blocks. Meanwhile, they have lots of attractive advantages, such as large surface area, splendid stability and conjugate skeleton. As a research case, the aptasensor based on CPOP-2 with the large porous skeleton exhibits the excellent electrochemical detection behavior toward penicillin (PCL). More importantly, this aptasensor can quantitatively detect trace PCL in actual test samples.
