Using click reaction to covalently link heterogeneous gold nanorods into head‐to‐head one‐dimensional chains with an alternating sequence as plasmonic Fano resonators

We present the deterministic linkage of short and long gold nanorods into one-dimensional (1D) alternating nanorod chains in a head-to-head manner using click reactions. By precisely controlling surface chemistry, we achieve orientation-specific robust covalent between with high-product yield. The optical response exhibits Fano-like resonances. This method enables high-throughput production covalently linked plasmonic particle networks consisting heterogeneous nanoparticles specifically chosen spectral responses.
