The Era Beyond Fluorescence and Phosphorescence – Thermally Activated Delayed Fluorescence

Advances in knowledge about light emission have brought breathtaking innovations in lighting and display technologies. The well-known light-emitting processes are fluorescence and phosphorescence. Let’s take a closer look into their dynamics and another light-emitting process: Thermally Activated Delayed Fluorescence (TADF)!

Stacks on stacks on stacks

Finding ways to create order is a common theme in science. Here researchers are trying to carefully arrange chromophores in order to create better solar cells (among other potential uses). In particular, these chemists are trying to make porphyrins stand up on a surface creating stacks of porphyrins that are a well defined distance from each other and from the surface they are attached to.

Copper (I) Hydroxide–Cuprice

Chemists probably would not willingly search for CuOH unless there is some theoretical basis for its existence. Without changing the oxidation states, a readied reaction could be 2 CuOH –> Cu2O + H2O. Its existence has been speculated on, now the really interesting work begins with the compound’s isolation (for a synthetic chemist).
