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.
