TL;DR: Tritiated fluorenone 2 was prepared from 2-iodofluorenone 1 by halogen-tritium exchange with specific activity of 17 Ci/mmol and gave the corresponding tritiated fluorenol 3.
Abstract: Tritiated fluorenone 2 was prepared from 2-iodofluorenone 1 by halogen-tritium exchange. The product had specific activity of 17 Ci/mmol. The product 2(after dilution with unlabeled congener) on reduction with NaBH4gave the corresponding tritiated fluorenol 3.

TL;DR: In this paper , a new series of extended linkers containing polyaromatic chromophores (biphenyl, naphthalene, anthracene, fluorene, 9,9-dimethylfluorene and fluorenone) functionalized with isonicotinoyl moieties have been synthesized by Pd-catalyzed cross-coupling reactions involving isonicamide and the appropriate aromatic dibromide.
Abstract: In this study, a new series of extended linkers containing different polyaromatic chromophores (biphenyl, naphthalene, anthracene, fluorene, 9,9-dimethylfluorene and fluorenone) functionalized with isonicotinoyl moieties have been synthesized by Pd-catalyzed cross-coupling reactions involving isonicotinamide and the appropriate aromatic dibromide. The optimized protocol led to the isolation of the target molecules in good yield and with high purity. These were characterized by 1H NMR, FTIR, MS, and elemental analysis and their solid state structures were solved by single-crystal X-ray diffraction analysis. Electronic absorption and emission spectra were collected both in solution (DMF) and in the solid state. TDDFT calculations were carried out to investigate the effect of the isonicotinoyl moieties on the spectral features of the central chromophores. Although in solution only the linker containing a fluorenone scaffold shows a weak fluorescence, all the isolated linkers turned out to be fluorescent in the solid state, thus paving the way for their use for the fabrication of fluorescent MOFs.

TL;DR: In this article, aryloxymesitylchlorogermanes was synthesized either by intramolecular dehydrohalogeneation between mesityltrichlorogermane and corresponding alcohols or phenols, or by transmetallation.

TL;DR: In this article, the authors proposed a fluorenone (FL) approach to deal with acetonitrile and Hammett's 3FL* and N-dimethylaniline (NDILINE) characters.
Abstract: 在 acetonitrile 的 fluorenone (FL ) 的最低激动的三位字节状态的性质，乙醇醋酸盐，甲苯，环己烷用解决时间的激光闪光光分解作用被调查了。相应阳离子激进分子和阴离子激进分子的外观建议电子转移反应发生在 3FL* 和胺之间。试验性的结果与减少溶剂极性一起在熄灭的率常数显示出减少。熄灭 FL 的率常数的变化与三 N 使三位字节激动， N-dimethylaniline 衍生物用 Hammett 常数被解释。
