Layer‐by‐layer assembly of gold nanoparticle/dendrimer composite films is described in this article. Crosslinking the nanoparticles through disulfide‐functionalized polyphenylene dendrimers enables well‐controlled film deposition and serves to mechanically reinforce the film material. Chemiresistors based on such films (see Figure) display short response times, high sensitivity to volatile organic compounds, and a desirable low sensitivity to humidity.
