TECHNOLOGY FOCUS - POLYMERS - Preferred Component: The molecularly imprinted conjugated polymer has selectivity functionality and transducer functionality. The molecularly imprinted polymer comprises cavities, which have a shape, a size, and functional groups dependent on a template molecule used during a polymerization reaction for forming the molecularly imprinted conjugated polymer. The molecularly imprinted conjugated polymer is a derivative of a conjugated polymer, which comprises a unit(s) consisting of thiophene, fluorene, arylene, heteroarylene, and/or vinylene. Preferred Method: Forming a partially converted conjugated polymer is performed in a solution or a thin film. It comprises reacting a solution of monomers with a basic compound to form a precursor polymer; and partially converting the precursor polymer, where a partially converted conjugated polymer is obtained. Grafting a first molecularly imprinted polymer onto the partially converted conjugated polymer comprises irradiating the partially converted conjugated polymer with UV light, forming a conjugated macroiniferter radical; and reacting the conjugated macro-iniferter radical with a first and a second monomer in the presence of a template molecule. The method comprises removing the template molecule; and grafting a second molecularly imprinted polymer onto the partially converted conjugated polymer. Removing the template molecule comprises performing a washing step. EXAMPLE - The conjugated macro-iniferter polymer was added with distilled monomer e.g. methyl methacrylate (MMA), a cross-linker monomer e.g. ethylene glycol dimethacrylate (EGDMA), and a template molecule e.g. D- or L-phenylalanine anilide. The solution was degassed by three freeze-pump-thaw cycles. The polymerization was initiated by irradiation with an ultrahigh pressure mercury UV lamp for a given time at room temperature under nitrogen atmosphere. The polymer was precipitated in methanol at 0degreesC, collected, and dried in vacuum. The polymer was washed with a solvent to eliminate the template molecule, to obtain a bulk material that was a molecularly imprinted conjugated polymer.
