Two hypercrosslinked microporous carbazole-based polymers for electrochemical recognition of penicillin

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.

Automated summary

Two hypercrosslinked microporous carbazole-based polymers (C-POP-1 and C-POP-2) were synthesized using an efficient Friedel-Crafts coupling approach. The porous structures of the polymers were controlled by regulating the length of two-node linear organic blocks. The aptasensor based on C-POP-2 demonstrated excellent electrochemical detection behavior for penicillin, allowing for quantitative detection of trace penicillin in real samples.
