The resulting structures [<jats:bold>L<\/jats:bold><jats:sub>2<\/jats:sub>Ca], [<jats:bold>L\u2032<\/jats:bold><jats:sub>2<\/jats:sub>Ca], and [<jats:bold>L\u2032\u2032<\/jats:bold><jats:sub>2<\/jats:sub>Ca] represent the first examples of enantiopure homoleptic calcium complexes based on this type of ligands. The calcium complexes show blue\u2013green photoluminescence (PL) in the solid state, which is especially bright at low temperatures. Whereas the emission of [<jats:bold>L\u2032\u2032<\/jats:bold><jats:sub>2<\/jats:sub>Ca] is assigned to the fluorescence of naphthyl groups, the PL of [<jats:bold>L<\/jats:bold><jats:sub>2<\/jats:sub>Ca] and [<jats:bold>L\u2032<\/jats:bold><jats:sub>2<\/jats:sub>Ca] is contributed by long\u2010lived phosphorescence and thermally activated delayed fluorescence (TADF), with a strong variation of the PL lifetimes over the temperature range of 5\u2013295\u2005K. Furthermore, an excellent catalytic activity was found for these complexes in hydroboration of ketones at room temperature, although no enantioselectivity was achieved.<\/jats:p>","DOI":"10.1002\/chem.202004833","type":"journal-article","created":{"date-parts":[[2020,12,24]],"date-time":"2020-12-24T08:58:44Z","timestamp":1608800324000},"page":"4401-4411","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["Enantiopure
