In order to apply gold nanoparticles to the materials for electronic and optical devices, they are required to be tolerant of heat applied in the fabrication processes. In our previous study, novel gold nanoparticles with excellent thermal stability were developed by introducing an amide bond and a condensed ring into the ligand molecules. On the other hand, particle size is a key factor in determining device performance, gaining control over the size is highly advantageous. In this study, a size-increase reaction of the pyrene-containing gold nanoparticle was carried out. The particle size was successfully increased from 2 to ca. 10 nm, without lowering the thermal stability. Furthermore, their interligand interactions could be probed using fluorescence measurements based on the characteristic excimer emission of pyrene. It is suggested that strong π–π stacking occurred around the particles, even after the size-increase reaction, contributing to maintaining the thermal stability.
