Selectivity

Cerium metal-organic framework with amino linkers achieves 100% selective photoreduction of CO2 to CO at 126 μmol·g-1·h-1 via transient Ce(III) sites and reversible binding.

Selective resonance ionization technique using angular momentum selection rules and polarized light enables isolation of rare calcium isotopes Ca-43 and Ca-41 while suppressing abundant Ca-40.

Photoredox-catalyzed deoxytrifluoromethoxylation installs OCF3 groups on phenols via in situ difluorophosgene generation and aryl carbonofluoridate activation.
