The immobilization of organocatalysts is one of the most remarkable and unique steps for their efficient use in asymmetric transformations. The challenges of synthesizing organocatalysts, the limitations of their isolation from the reaction medium, and the limited reusability of these catalysts in homogeneous systems have made the development of novel immobilization strategies inevitable. In the first part of this thesis, a novel approach for the anchoring of cinchona alkaloid-based organocatalysts via click-type reactions is demonstrated. Organocatalyst-bearing monomeric structures were synthesized and successfully polymerized using the electrochemical polymerization method to obtain electroactive, heterogeneous catalyst films. Then, the redox properties of these polymeric materials were investigated with cyclic voltammetry. Design and synthesis of conjugated polymers for sensing applications offer a rapid, selective, and cost-effective strategy for the detection of metal ions. In the second part of this thesis, a novel thiol-functionalized monomer was synthesized, and its potential sensing abilities over various metal ions were investigated. Synthesized monomeric structure was polymerized electrochemically, and its redox properties were investigated.
