1,1,1,3,3,3-Hexafluoro-2-propanol (HFIP) rose through the ranks of organic solvents because of its unique set of physicochemical properties, becoming a solvent of choice in dominant areas of homogeneous catalysis, including acid catalysis, transition metal catalysis, photocatalysis, and organocatalysis. Its use not only allows re-imagining of well-established transformations but also unlocks eluding ones, representing new opportunities for future synthetic development.

Photoluminescence (PL) is a property of great interest in science and technology. Here we review recent approaches for the control of fluorescence and phosphorescence by tailored supramolecular environments. Taking recent examples from solid-state materials as applied in organic light-emitting diodes (OLEDs), supramolecular complexes, cyclophanes, foldamers, and protein–dye complexes, as well as DNA and RNA aptamers, we showcase how specific ‘smart’ matrices can modulate PL properties including brightness, quantum yield, wavelength, and lifetime. From the examples collected in this review it becomes evident that, by means of an advanced understanding of specific interactions of chromophores with the surrounding matrix, relevant processes in the excited state can be controlled in a desired way, leading to improved light-emitting materials.

Sulfonyl fluorides are now established click reagents that find broad applications in synthesis, chemical biology, and drug discovery. Sulfonyl fluorides owe their popularity to their increased stability compared with their sulfonyl chloride cousins and…

Isomeric covalent organic frameworks (Iso-COFs) represent an emerging class of crystalline porous polymers that possess identical chemical compositions but different framework structures. Iso-COFs have garnered significant attention for their tunable…
