“…Thus, use of long alkane thiols or alkane thiols containing polar head groups can increase the stability of the MIM. Another approach to increasing the stability of MIMs is to cross-link the surface layer as shown by Luo et al (2006). They used MPTS to form a MIM on the gold surface via the thio group, and in the subsequent step, cross-linked the MPTS layer via O-Si-O bonds formed between adjacent siloxanes using an aqueous solution containing 50% ethanol at pH 8.…”

“…Rogers and coworkers (Luo et al ., ) reported pyrene imprinted monolayers formed using the one‐step procedure with different long chain alkane‐thiols (1‐hexadecanethiol, 11‐mercapto‐undecanoic acid and 11‐mercaptoundecanol) and pyrene as template. Pyrene was removed by immersing the MIM in toluene and then ultrasonicated, followed by rinsing with ethanol.…”

A comprehensive report on molecularly imprinted monolayers (MIMs) is presented, but does not include bulk-polymer thin film coatings on surfaces, inorganic surface imprinting, polymer grafting and layer-by-layer methods. Due to difficulties in imprinting large molecules and obtaining fast binding responses with traditional network polymer materials, MIMs have been developed with the aim of enhancing mass-transfer of analytes in imprinted materials. Three approaches to MIM fabrication have been developed with respect to the formation of the pre-organized template-matrix complex. In the first approach, the molecular binding sites are formed in a monolayer on a glass or gold surface. The second approach uses a template-macromolecule complex to form binding sites in the solution phase that are immobilized onto a surface; and the third approach transfers an imprinted Langmuir film onto a gold surface. Mass transfer in these MIMs in most cases is on the order of minutes, and both small and large molecules (proteins) have been imprinted.

The feasibility of using thiol chemistry to form molecularly imprinted polymer-coated gold electrodes to measure pyrene is reported. For the first approach, poly(2-mercaptobenzimidazole) (2-MBI) was electrochemically deposited on gold electrodes in the presence or absence of the template pyrene. For the second approach, the pyrene derivative N-(1-pyrenyl)maleimide was covalently bound to 1,3-propane thiol that had been previously self-assembled on a cleaned gold surface. Resorcinol was then electrochemically polymerized onto the electrode followed by electrochemical stripping of the thiolated pyrene from the polymer-coated electrode. For both electrode configurations, the binding of pyrene to the MIP-coated electrode was detected indirectly through pyrene-dependent access of a ferricyanide probe to the electrode surface as measured using square-wave voltammetry.

A composite of reduced graphene oxide and pyrene‐imprinted polymer was synthesized and employed as a solid phase for extraction of five selected polycyclic aromatic hydrocarbons (PAHs) from water samples. Gas chromatography‐time of flight/mass spectrometry was employed in the analysis of the extracts. The composite was prepared by a free radical polymerization of methacrylic acid and 4‐vinylpyridine as monomers and ethylene glycol dimethacrylate as a crosslinker. The adsorption studies were carried out through batch binding studies. The binding capacity for the imprinted and non‐imprinted composite was 101.83 and 68.21 µg g−1, respectively. The adsorption followed the pseudo 2nd order and well fitted the Langmuir isotherm. Mean recoveries ranging from 73% to 105.4% for both spiked deionized water and environmental water samples were obtained when the imprinted composites were employed in solid phase extraction of the PAHs. The composites could be re‐used for five times without a significant loss in recoveries. The proposed method was employed for the analysis of spiked environmental water samples and did not show significant changes in the recoveries showing there were no matrix interferences. © 2017 Wiley Periodicals, Inc.
