Covalent layer-by-layer (LbL) thin films with the well-defined charge-transfer (CT) chromophores were fabricated by the highly efficient [2 + 2] cycloaddition-retroelectrocyclization (CA-RE) reaction between the dialkylaniline-substituted alkynes and 7,7,8,8-tetracyanoquinodimethane (TCNQ) moieties. The resulting thin films showed potent redox activities and Ag ion sensing ability due to the formed CT chromophores.
通过二烷基苯胺取代的炔烃与7,7,8,8-四氰基对苯二醌二甲烷(TCNQ)部分之间高效的[2 + 2]环加成-逆电环化(CA-RE)反应,制备了具有明确电荷转移(CT)发色团的共价层层(LbL)薄膜。由于形成了CT发色团,所得薄膜表现出强大的氧化还原活性和银离子传感能力。
