Flexible and luminescent fibers of a 1D Au(I)-thiophenolate coordination polymer and formation of gold nanoparticles-based composite materials for SERS

Popis výsledku v původním jazyce

The synthesis and characterizations of free-standing fibers of a Au(I)-based coordination polymer (CP) are reported. The flexible fibers of the 1D gold(I)-thiophenolate [Au(SPh)]n CP have an average diameter of 270 nm and length of few micrometers. They are hydrophobic because of the presence of the phenyl rings and due to the strong Au(I)-S interactions, they are highly stable under extreme acidic and basic conditions. These fibers are also red-emissive at room temperature related to the presence of aurophilic interactions. In addition, a composite material can be easily obtained through controlled calcination approach, resulting in the formation of gold nanoparticles (AuNPs) on the fibers surface. Owing to the plasmonic resonance of AuNPs, this composite material exhibits good sensitivity towards the detection of molecules as observed through surface enhanced Raman scattering (SERS).
