Abstract
A novel fluorescent poly(2,7-carbazole) with a 4-[tris-(4-octyloxyphenyl)methyl]phenyl side chain is used to detect the explosive compounds TNT and DNT. It shows high recycled fluorescence quenching sensitivity, which is due to its strong electron donating ability and weaker interaction between the polymer chains caused by the bulky side chain.
