A stable dialkylgermanone was generated by mixing a solid of the corresponding dialkylgermylene and gaseous NO. While the dialkylgermanone is marginally persistent in solution and gradually converts to its head-to-tail dimer at room temperature, the addition of THF to the dialkylgermanone provided an isolable THF-coordinated dialkylgermanone. The THF-coordinated dialkylgermanone reacts with HO, THF, and B(CF) similar to the corresponding base-free two-coordinate dialkylsilanone.

Interestingly, the CN-group-substituted 1,4-diphenylanthracene derivative was found to exhibit a higher fluorescence quantum yield ( = 0.71) in the solid state than in the solution state, probably due to the formation of an intermolecular Ar-CN⋯H-Ar hydrogen bond and antiparallel type locked packing structure in the solid state.

However, few reports have described characteristic endoscopic and histopathologic findings, and no small intestinal lesions have been reported so far.
Case Summary: A woman in her 60s with psoriasis was administered ixekizumab (IXE), an anti-IL-17A antibody, for the treatment of psoriasis.
μ-Nitrido- and μ-carbido-bridged iron phthalocyanine dimers, when used as cathode-active materials for rechargeable lithium batteries, showed four stable redox waves in cyclic voltammetry studies in solution and a stable discharge capacity of approximately 60 mAh g after 200 cycles. These results indicate that μ-heteroatom-bridged iron phthalocyanine dimers are good platforms for designing novel phthalocyanine-based electrode-active materials.

Whereas the isomer ratio of the obtained cage mixture, consisting of up to 42 isomers, is insensitive to temperature and solvent, the quantitative convergence from the mixture to a single isomer is accomplished upon encapsulation of a large spherical guest, namely fullerene C. The observed isomerization with other guests depends largely on their size and shape (, <10 and 82% convergence with planar triphenylene and bowl-shaped corannulene guests, respectively).
