Functional Covalent Layer-by-Layer Thin Films by [2 + 2] Cycloaddition-Retroelectrocyclization.

Published in: ACS macro letters (2018)

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.
