Three novel bis(tetraphenylethene) (BTPE) derivatives 1–3 were efficiently synthesized. All the materials exhibited aggregation-induced emission characteristics, and the dynamic light scattering measurments proved that the average diameter of the oxidised analogues 2 and 3 was less than that of the thioether precursor 1 due to the oxidation of the linking S-atom. Linking two tetraphenylethylenes via a sulfur atom with different oxidation states offered compounds which showed reversible mechanofluorochromic behavior. The crystal-to-amorphous phase conversion process was responsible for the mechanofluorochromism. Most notably, sulfone-based BTPE 3 presented polymorphism due to different packing modes, and the three observable morphologies could be interconverted.

A scalable reduction of sulfoxides to sulfides in a sustainable way remains an unmet challenge. This report discloses an electrochemical reduction of sulfoxides on a large scale (>10 g) under mild reaction conditions. Sulfoxides are activated using a substoichiometric amount of the Lewis acid AlCl3, which could be regeneratedviaa combination of inexpensive aluminum anode with chloride anion. This deoxygenation process features a broad substrate scope, including acid-labile substrates and drug molecules.

In this work, the transfer of the flexible and easily tunable hierarchical structure of nickel organochalcogenides to different binary Ni-based nanomaterials via selective coupling of organic units was developed. We suggested the use of substituted aryl groups in organosulfur ligands (SAr) as traceless structure-inducing units to prepare nanostructured materials. At the first step, it was shown that the slight variation of the type of SAr units and synthetic procedures allowed us to obtain nickel thiolates [Ni(SAr)2]n with diverse morphologies after a self-assembly process in solution. This feature opened the way for the synthesis of different nanomaterials from a single type of precursor using the phenomenon of direct transfer of morphology. This study revealed that various nickel thiolates undergo selective C-S coupling under high-temperature conditions with the formation of highly demanding nanostructured NiS particles and corresponding diaryl sulfides. The in situ oxidation of the formed nickel sulfide in the case of reaction in an air atmosphere provided another type of valuable nanomaterial, nickel oxide. The high selectivity of the transformation allowed the preservation of the initial organochalcogenide morphologies in the resulting products.
