The grant financed by National Science Center (no. 2021/43/B/ST5/00753) is realized in the form of scientific consortium with Wrocław University of Science and Technology
The description of the project (in Polish) is available at https://projekty.ncn.gov.pl/opisy/539425-pl.pdf while below we will present crucial data, publications and other.
The quadrupolar cores were opptimized and their properties were studied with the use of quantum-chemical methods. That gave hints towards synthesis of the most interesting ones.

It is fascinating that the AIE and ACQ properties of molecules can be switched by the topology of the molecule. We have reached such an effect by the replacement of mild acceptor (CF3) and mild donor (OMe) in the benzothiazole core.
