摘　　要：C02-controlled assembly of conjugated polymer and boron nitride(BN)was fabricated via electrostatic and hydrophobic interactions between the BN fiber and conjugated polymer of PFBT containing fluorene units and 2,1,3-benzothiadiazole units.C02,an effective and green stimulus for regulating the assembly of PFBT and BN fibers,leads to an obvious fluorescence variation.Moreover,PFBT enables the assembly with the signal amplification and light-harvesting properties.This work provides a new triggering method to construct intelligent conjugated polymer-based platform,and offers fluorescence monitoring strategy for carbon dioxide capture.C02-controlled assembly of conjugated polymer and boron nitride(BN) was fabricated via electrostatic and hydrophobic interactions between the BN fiber and conjugated polymer of PFBT containing fluorene units and 2,1,3-benzothiadiazole units.C02,an effective and green stimulus for regulating the assembly of PFBT and BN fibers,leads to an obvious fluorescence variation.Moreover,PFBT enables the assembly with the signal amplification and light-harvesting properties.This work provides a new triggering method to construct intelligent conjugated polymer-based platform,and offers fluorescence monitoring strategy for carbon dioxide capture.
