    • Molecules 1 and 2a show the opposite electrostatic potential distribution. Although this may result in differences in the template/analyte electrostatic interactions with the imprinted cavity, our experimental results demonstrated that the matching shape/size is a dominant factor.

    • Alternatively, the decrease in conjugation length may be due to cross-conjugation in meta-substituted cross-linker units, which disrupts the π-electron conjugation in the ground state (but enhances the conjugation in the excited state; see: Thomson, A. L.; Gaab, K. M.; Xu, J.; Bardeen, C. J.; Martinez, T. J. J. Phys. Chem. A 2004, 108, 671-682). This effect requires further studies which will be reported elsewhere.

    • Diffusion-controlled analyte penetration from the surface into the bulk of the solid material will depend on the solubility of the analyte in the polymer and may also affect the quenching efficiency, especially at longer exposure times. Still, considering the relative similarity between the polymers under study, it is expected to provide only a minor contribution
