A new study in Communications Materials — including Cluster Postdoctoral Researcher Nils Rosemann and Principal Investigators Jasmin Aghassi-Hagmann and Stefanie Dehnen — demonstrates the first successful inkjet printing of adamantane-type organotin sulfide clusters without altering their molecular identity. These clusters exhibit unusual optical properties, producing either white light or frequency doubling depending on their structure. The researchers overcame the longstanding challenges of instability and poor solubility by combining phenyl groups, which improve optical performance, with alkyl chains, which improve solubility. This breakthrough paves the way for printable, reusable, and thermally stable optical data storage materials.
