have been prepared by grafting of molecularly imprinted polymers (MIPs) from dithiocarbamate-modified porous silica supports. The living properties of the system are demonstrated by consecutive grafting of two polymer layers imprinted with chiral templates. The enantioselectivity of the first layer is reversed by grafting a second layer imprinted with the antipode. (B. Sellergren et al., September 3, Adv. Mater. 2002, 14, 1204-1208)
