AbstractNovel molecular recognition materials were prepared from commercially available Torlon® 4000T polyamide–imide by an alternative molecular imprinting. Torlon® 4000T was converted into the molecularly imprinted film adopting 9-ethyladenine as a print molecule, whereby the adenosine recognition site was formed. The molecular recognition phenomena were studied by SPR spectroscopy. The apparent affinity constant toward adenosine, estimated by using apparent adsorption isotherms, ranged from 2.73×104 to 7.86×104 mol−1 dm3. The present work demonstrates that SPR spectroscopy is a facile method for the study of molecularly imprinted materials. The results obtained in the present study also suggest that Torlon® 4000T is one of the more highly effective candidate materials to be converted into molecular recognition materials by applying an alternative molecular imprinting.
