A subset of coordination cages have garnered considerable recent attention for their potential permanent porosity in the solid state. Herein, we report a series of functionalized carbazole-based cages of the structure type M12(R-cdc)12 (M = Cr, Cu, Mo) where the functional groups include a range of aromatic substituents. Single-crystal X-ray structure determinations reveal a variety of intercage interactions in these materials, largely governed by pi-pi stacking. Density functional theory for a subset of these cages was used to confirm that the nature of the increased stability of aryl-functionalized cages is a result of inter-cage ligand interactions.

Disclosed in the present application is an organic mixture. The organic mixture comprises two organic compounds H1 and H2. The organic compound H1 has electron transmission performance, and the organic compound H1 satisfies: Δ((LUMO+1)?LUMO)≥0.1 eV, and min((LUMO(H1)?HOMO(H2), LUMO(H2)?HOMO(H1))≤min(ET(H1), ET(H2)). The organic compound H1 and the organic compound H2 are easy to form exciplexes and have balanced electron transmission properties, the organic compound Hi has high stability of electron transmission, and accordingly the efficiency and the service life of related electronic components can be effectively improved, and a feasible solution for improving overall performance of the electronic components is provided.
A Rh(III)-catalyzed C-H activation of boronic acid with aryl azide to obtain unsymmetric carbazoles, 1H-indoles, or indolines has been developed. The reaction constructs dual distinct C-N bonds via sp2/sp3 C-H activation and rhodium nitrene insertion. Synthetically, this approach represents an access to widely used carbazole derivatives. The practical application to CBP and unsymmetric TCTA derivatives has also been performed. Mechanistic experiments and DFT calculations demonstrate that a five-membered rhodacycle species is the key intermediate.
