Synthetic receptor materials having selective separation abilities by guest recognition have been well documented and expected to be a promising tool for separation and analytical methods. As a tailor made tool for artificial receptor, imprinting technique can provide effective method for such advantageous functional materials, which selectively recognizes and separates a target molecule from mixture solution. We have developed that the membrane technique of hybrid-molecular imprinting becomes to be very useful for tailor made separation by polymeric scaffold membrane. Successfully we performed by only mixing imprinted polymer powders with scaffold polymer, which was available for porous membrane. Such advantage resulted in effective uses for applications to removal to chemicals targeted to endocrine disruptor, bisphenol derivatives, indole derivatives and tocopherole. In cases targeted for the bisphenol derivatives, permselective membrane operation enabled smart separation by using porous polysulfone membrane materials. A brief review of the importance of hybrid-molecule imprinting and an example relating molecule recognition and separation by the imprinted membranes would be presented.
