Microcontact Printing of CdS/Dendrimer Nanocomposite Patterns on Silicon Wafers

Micrometer‐scale patterns of blue photoluminescing CdS nanoparticles can be produced by microcontact printing on a hydroxyl‐terminated silicon wafer surface (see Figure). The CdS nanoparticles were synthesized with amine‐terminated generation eight dendrimers as stabilizers. The resulting CdS/dendrimer composite is directly printable due to hydrogen bonds between dendrimer and surface.
