摘要：

A facile and efficient methodology for the formation of polymer-fullerene networks via a light-induced reaction is reported. The photochemical crosslinking is based on a nitrile iminemediated tetrazole-ene cycloaddition reaction, which proceeds catalyst-free under UV-light irradiation (lambda(max) = 320 nm) at ambient temperature. A tetrazole-functionalized polymer (M-n = 6500 g mol(-1), D = 1.3) and fullerene C-60 are employed for the formation of the hybrid networks. The tetrazole-functionalized polymer as well as the fullerene-containing networks are carefully characterized by NMR spectrometry, size exclusion chromatography, infrared spectroscopy, and elemental analysis. Furthermore, thermal analysis of the fullerene networks and their precursors is carried out. The current contribution thus induces an efficient platform technology for fullerene-based network formation.
