Efficient fluorescence of alkali metal carbazolides

Abstract

The sterically demanding 1,8-bis(3,5-ditertbutylphenyl)-3,6-di-tert-butylcarbazole (dtbpCbz)–H was deprotonated with various metal bases to obtain a complete series of thermally robust alkali metal compounds of the type [(dtbpCbz)M] (M = Li, Na,...

Hydride Abstraction from a BH4– Anion in a Carbazolyl Lanthanum Boranate

“…Our group introduced the bis-arene-substituted carbazolyl ligand 1,8-bis(3,5-di- tert -butylphenyl)-3,6-di- tert -butyl-carbazolyl ( dtbp Cbz), which has already been applied to s-, p-, and d-block-element chemistry. − As the bulky dtbp Cbz ligand mainly acts as a classic monodentate amide σ donor that could even accommodate the large Ba 2+ cation in that position, coordination of a lanthanide ion without any coligands could be feasible as well. However, the initial attempts to generate dtbp Cbz lanthanide complexes by employing LnCl 3 as precursors were futile.…”
