The development and investigation of (supra) molecular‐based architectures characterized
by light‐activated functionalities is a highly relevant topic of chemical research. The interest …

Chemical reactions in confined environments are important in areas as diverse as
heterogenous catalysis, environmental chemistry and biochemistry, yet they are much less …

We report a new class of arylazopyrazolium-based ionic photoswitches (AAPIPs). These
AAPIPs with different counter ions have been accessed through a modular synthetic …

Light is an exceptional external stimulus for establishing precise control over the properties
and functions of chemical and biological systems, which is enabled through the use of …

Photochemical studies on supramolecular hosts that can encapsulate small guest molecules
commonly focus on three aspects: photoswitching the cage to release or trap the guest, the …

Ultrafast transient absorption spectroscopy reveals new excited-state dynamics following
excitation of trans-azobenzene (t-Az) and several alkyl-substituted t-Az derivatives …

Light-responsive materials capable of undergoing photoinduced molecular transformation
are excellent candidates for energy storage. Herein, we report a promising new liquid …

Multiple-resonance thermally activated delayed fluorescence (MR-TADF) emitters are
becoming increasingly attractive due to their applications in high-resolution organic light …

Natural UV photoprotection plays a vital role in physiological protection. It has been reported
that UVC radiation can make resveratrol (RSV) and piceatannol (PIC) accumulate in grape …

This Feature Article highlights the role of spatial confinement in controlling the fundamental
behavior of molecules. Select examples illustrate the value of using space as a tool to …
