摘要：

Colloidal gold nanoparticles self-assembled into macroscopic aggregates by charge-transfer interaction between pyrenyl units as an electron donor immobilized on the surface of the gold nanoparticles and a bivalent linker containing two dinitrophenyl units as electron acceptors. Transmission electron microscopy and scanning electron microscopy images showed the spherical aggregates consisting of the gold nanoparticles. The UV-vis absorption spectrum showed a thermally reversible self-assembly process.
