MECHANOLUMINESCENT AND MECHANOCHEMICAL PROCESSES IN THE CpZrCl–ORGANOALUMINUM COMPOUNDS SYSTEM

The photo- and mechanoluminescent characteristics of catalytic systems comprising zirconocene dichloride and organoaluminum compounds (AOC) was study. It was found that the addition of AlBu to CpZrCl leads to the appearance of additional luminescence bands, which indicates the formation of light-emitting products of mechanochemical reactions. Intense sonotriboluminescence was detected during ultrasonic treatment of a suspension of CpZrCl crystals in hexane. Ultrasound generates cavitation shock waves that accelerate and collide suspension microcrystals, causing their destruction, as well as local electrification with microdischarges and subsequent luminescence. The development of research in the field of mechanochemical transformations during mechanical action in heterogeneous systems with accompanying sonotriboluminescence can lay the foundation for the creation of new methods of luminescent control over the course of catalytic processes involving metal complexes and AOC.
