Ermolaev, Nikolai L. published the artcileTris(trifluoromethyl)germylethynyl derivatives of biphenyl and anthracene: Synthesis, structure, and evidence of the intramolecular charge transfer on the germanium center, Category: naphthyridine, the publication is Journal of Organometallic Chemistry (2015), 83-95, database is CAplus.
Sym. and unsym. 4,4′-disubstituted 1,1′-biphenyl, and 9,10-anthracene derivatives with tris(trifluoromethyl)germylethynyl -C顚咰Ge(CF3)3 substituents have been prepared, their properties have been studied and compared with those of dimethyl(phenyl)silylethynyl -C顚咰Si(Ph)Me2 compounds UV-visible absorption, steady-state, and time-resolved fluorescence spectra in solution for this germanium and silicon compounds have been investigated. The process of photoinduced electron-transfer from the aromatic group to the germanium center has been found in the unsym. 4-biphenyl -C顚咰Ge(CF3)3 mol. Anthracene derivatives with -C顚咰Ge(CF3)3 substituents have been characterized crystallog.
Journal of Organometallic Chemistry published new progress about 18512-55-5. 18512-55-5 belongs to naphthyridine, auxiliary class Alkynyl,Anthracene, name is 9,10-Diethynylanthracene, and the molecular formula is C18H10, Category: naphthyridine.
