SummaryHerein we present a survey of the literature covering the development of molecular imprinting science and technology over the years 2004 to 2011. In total, 3779 references to the original papers, reviews, edited volumes and monographs from this period are included, along with recently identified uncited materials from prior to 2004 which were omitted in the first instalment of this series covering the years 1930 to 2003. 1 In the presentation of the assembled references, a section presenting reviews and monographs covering the area is followed by sections describing fundamental aspects of molecular imprinting including the development of novel polymer formats. Thereafter, literature describing efforts to apply these polymeric materials to a range of application areas is presented. Current trends and areas of rapid development are discussed.2

A catalytic and positively thermosensitive molecularly imprinted polymer is reported. This unique imprinted polymer was composed of 4‐nitrophenyl phosphate‐imprinted networks that exhibited a thermosensitive interpolymer interaction between poly(2‐trifluoromethylacrylic acid) (PTFMA) and poly(1‐vinylimidazole) (PVI), which contains catalytically active sites. At a relatively low temperature (such as 20 °C), this imprinted polymer did not demonstrate significant catalytic activity for the hydrolysis of 4‐nitrophenyl acetate due to the interpolymer complexation between PVI and PTFMA, which blocked access to the active sites of PVI and caused shrinking of the polymer. Conversely, at higher temperatures (such as 40 °C), this polymer showed significant catalytic activity resulting from the dissociation of the interpolymer complexes between PVI and PTFMA, which facilitated access to the active sites of PVI and inflated the polymer. Unlike previously reported poly(N‐isopropylacrylamide)‐based molecularly imprinted polymers, which demonstrated decreased molecular recognition and catalytic activity with increased temperatures, i.e., negatively thermosensitive molecular recognition and catalysis abilities, this imprinted polymer exploits the unique interpolymer interaction between PVI and PTFMA, enabling the reversed thermal responsiveness.

“…Temperature‐programmed desorption (TPD) experiments were carried out to evaluate the interaction between MIPs and substrate (including the template and its analogue) using gas chromatography and a data processing system (Agilent 5890, USA) 18. First, the imprinted polymers (200 mg) were placed into an online U‐shaped quartz tube (4 mm I.D.).…”

Modulated molecular recognition was achieved in a temperature-sensitive molecularly-imprinted polymer. Using PNIPA as the temperature-sensitive element, the adenine-imprinted polymer (i.e., MIP-S) was prepared and characterized. The MIP-S exhibited a temperature-responsive molecular recognition behavior because of the thermal phase-transition within the MIP-S network. Specifically, below the transition temperature (e.g., 20 C), the MIP-S showed a highly specific recognition for the imprint species (adenine). However, the MIP-S did not show any significant resolution for the imprint species (adenine) and its analogue (1-methyladenine) above the transition temperature (e.g., 40 C). Such temperature-regulated recognition is comparable to a switch-on and switch-off process, thereby making tunable molecular recognition feasible.
