Low temperature chemical transformations of solids using high-energy intermediates have enabled the synthesis of a new series of layered oxide chalcogenide containing oxidised chalcogenide dimers promising a new range of solids.

A novel polymer material PEDOT:DBSA was prepared using oxidative polymerization and was modified by cross-linker GOPS and H₂SO₄-posttreatment. This material exhibits biocompatibility toward cell culture comparable to the glass substrate. The cross-linking process resulted in complete stabilization of PEDOT:DBSA thin film in an aqueous environment, whereas such stabilization was achieved even without high-temperature treatment. The model OECT device proved that the proposed material possesses electrical properties comparable to or even better than other organic mixed conductors used for transistors. This all shows a great potential of PEDOT:DBSA for bioelectronics applications.

Synthesis can be used to harness excited states and molecular functional materials. Supramolecular chemistry can provide an additional dimension of control to the excited states and expand the library of excited-state functional materials.

Conductive materials with tissue-matched softness are needed for ultra-soft electronics. Here, the authors report ultra-soft and conductive bottlebrush elastomer composites and fabricate them into electronics with laser cutting and 3D printing methods.
