Room-Temperature Phosphorescence Vapochromism through Conformational Control Open
Solid-state room-temperature phosphorescence is rarely observed in organic molecules, and the modification of its color upon application of physical or chemical stimuli is hardly achieved. In this work, we demonstrate that a decorated pers…

Unravelling the Role of Structural Factors in the Luminescence Properties of Persulfurated Benzenes Open
Room temperature phosphorescence rarely occurs from pure organic molecules, especially in the solid‐state. A strategy for the design of highly emissive organic phosphors is still hard to predict, thus impeding the development of new functi…

“The Sulfur Dance” Around Arenes and Heteroarenes ‐ the Reversible Nature of Nucleophilic Aromatic Substitutions Open
We disclose the features of a category of reversible nucleophilic aromatic substitutions in view of their significance and generality in dynamic aromatic chemistry. Exchange of sulfur components surrounding arenes and heteroarenes may occu…

A high-sensitivity long-lifetime phosphorescent RIE additive to probe free volume-related phenomena in polymers Open
The photophysical behaviour of phosphorescent rigidification-induced emission (RIE) dyes is highly affected by their micro- and nanoenvironment. This is exploited to monitor physical ageing and mechanical stresses in polymers.

Highly Emissive Water‐Soluble Polysulfurated Pyrene‐Based Chromophores as Dual Mode Sensors of Metal Ions Open
Pyrene‐based materials have gained considerable attention as stimuli‐responsive chemical sensors. We designed a polysulfurated arene system based on a tetra(phenylthio)pyrene core decorated with four carboxylic acid units. Three different …
