In this study, a series of chlorinated bridged ethers with varying numbers of sulfur and oxygen atoms were synthesized and their tunable photophysical properties in different aggregated states were investigated.
In this contribution, we describe a set of three chlorinated bridged ethers with varying numbers of sulfur and oxygen atoms. The substitution leads to highly emissive compounds with tunable photophysical properties in relationship to their state of aggregation, i. e. in solution, as aggregates and in the solid state. Additionally, an in-depth X-ray diffractometric analysis supported by a Hirshfeld study of non-covalent interactions and quantum chemical simulations was carried out. As the outcome, it was found that the content of sulfur in the compounds regulates the tuning of emission in solution as well as in the aggregated states as a consequence of their variation of planarity.
