a b s t r a c t A pyrene-imprinted polythiophene nanofilm is prepared by electrochemical deposition and used for highly sensitive detection of pyrene and its analogues. Using a molecular imprinting technique, pyrenespecific recognition sites are formed throughout the oligo/polythiophene film deposited onto a gold surface. These pyrene “imprints” possess complimentary geometric features to the analyte and are capable of forming -donor and hydrogen bonding interactions with pyrene. Upon exposure to pyrene, the functionalized nanosurface produces specific fluorescence emission whose response is linearly proportional to its concentration range between 0.01 and 1.0 M with good stability and reproducibility (relative standard deviation
