Based on our design of thermo-responsive polymer systems in organic solvents, an organic catalyst or a transition metal catalyst will be introduced into the polymer chain of the thermo-responsive polymers by copolymerization to construct an on-demand hybrid catalyst. Controlling dissolution or aggregation of the thermo-responsive part by the presence or absence of appropriate pseudo-solvating molecules, called effectors, will provide controlled ON-OFF catalytic ability of the catalytic part. The structural parameters of the on-demand hybrid catalysts such as molecular weight and copolymerization ratios will be optimized for drastic ON-OFF cut-off. Moreover, parallel use of these on-demand catalysts should access to more sophisticated control of some chemical reactions. In particular, I also aim to construct a catalyst that exhibits hetero-allosteric behavior by designing the on-demand hybrid catalyst in which the effector can be transformed to be a non-effector.
