Biopolymers, such as DNA, peptides and proteins, present a well-defined sequence regulation of repeat units which confers remarkable properties. However, nature's precision in regulating the molecular weight of these polymers has not been yet realized in synthetic chemistry. Herein, we report for the first time the synthesis of well-controlled multiblock copolymers of acrylates at room temperature via photoinduced living radical polymerization. The synthesis of a well-defined dodeca (12) block copolymer has been achieved, presenting quantitative yields and very narrow dispersities .  Minimal polymerization in the absence of light illustrates temporal control and alludes to potential application, one of the frontiers of materials chemistry, whereby precise spatiotemporal �on/off� control and resolution is desirable.
