Tuning the Emission Behaviour of Halogenated Bridged Ethers in Solution, as Solids and as Aggregates by Chalcogen Substitution

Von Wiley-VCH zur Verfügung gestellt

In this contribution we describe a set of three chlorinated bridged ethers with varying number of sulphur 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 outcome, it was found that the content of sulphur in the compounds regulates the tuning of emission in solution as well as in the aggregated states as consequence of their variation of planarity
