Coordination-Driven Self-Assembly on Polymer Surfaces for Efficient Synthesis of [Au(SPh)]_n Coordination Polymer-Based Films

Abstract

We describe a simple bottom-up strategy to generate [Au­(SPh)] n (SPh: thiophenolate) coordination polymer (CP) based thin films by employing an interfacial self-assembly on a nylon substrate. This method utilizes Au ion-doped nylon film as a precursor of [Au­(SPh)] n CP and a support substrate to control the kinetics of the reduction of the Au ion from Au­(III) to Au­(I) and the complexation of Au­(I) ions as well as SPh on the surface of the nylon film. The obtained CPs exhibit a fibril morphology with high crystallinity, which leads to a luminescent property. Further, we systematically study the formation mechanism of [Au­(SPh)] n CPs on the substrates. Amorphous CPs formed at an early stage of reaction are transformed to crystalline CPs based on the rearrangement of components during the reaction. The findings described herein offer novel and interesting openings for the synthesis of Au ion-based CPs that demonstrate desired functions for a wide range of applications.

“…What coordination chemists concentrate on for more than 20 years is the fundamental research, which is relevant to the crystalline coordination polymers' (CPs) design, preparation, and structural characterization. [4][5][6] The utilization of CPs is relatively diverse, including nonlinear optics, hydrogen storage, heterogeneous catalysis, drug delivery, selective separations, but not until recently, in the biomedicine aspect. [7][8][9][10][11] In terms of the aspect of exploratory synthesis, the ability is significant, due to the combination of anionic dicarboxylate ligands, divalent metal ions, and ancillary neutral dipyridyl ligands being used as precursor mixtures seems almost unlimited.…”
