Abstract

In this contribution, we merged a motif for solution and solid-state emission (SSSE) with thioethers capable of photocyclisation to combine efficient emission across several states of aggregation with tuneable phosphorescence. In addition, the bridged ethers revealed remarkable singlet oxygen quantum yields that increase with the chalcogen's atomic number.
