Synthesis of Octafluorobiphenyl-4,4′-dicarboxylic acid and photoluminescent compounds based thereon

Abstract

Octafluorobiphenyl-4,4'-dicarboxylic acid (H 2 L) and its complexes with Tb(III) and Eu(III) [Ln 2 (H 2 O) 4 (L) 3 ·3H 2 O and Ln 2 (phen) 2 (L) 3 ·2H 2 O] have been prepared; their structure has been elucidated from IR spectroscopy and X-ray diffraction analysis data. Thermal properties of the compounds have been studied. The complexes of Tb(III) and Eu(III) exhibit green and red photoluminescence, respectively.

A Bumper Crop of Boiling-Water-Stable Metal–Organic Frameworks from Controlled Linker Sulfuration

“…Just such a system is described here. Building on our longstanding effort in utilizing thiolate anions as facile nucleophiles for accessing functional building blocks for framework materials, − we set eyes on the perfluoronated substrate H 2 bpdc-8F (octafluorobiphenyl-4,4′-dicarboxylic acid; Figure ): this molecule was earlier made by Miljanic et al, but Larionov et al subsequently reported an easier synthesis entailing no expensive transition metal catalysts. As an initial test, we subjected the dimethyl ester of H 2 bpdc-8F to the simple sulfur nucleophile methylthiolate (Figure S1).…”
