Near Infrared Photoswitching by Direct Excitation—A Next Frontier

Angewandte Chemie International Edition, EarlyView.
Molecular photoswitches finally enter the spectral realm of near‐infrared for their direct excitation. This minireview summarizes the current state‐of‐the‐art, the design principles for achieving such low‐energy light responsiveness, and the unique applications that are unlocked by it.

Cover Feature: Molecular Switching in Confined Spaces: Effects of Encapsulating the DHA/VHF Photo-Switch in Cucurbiturils (Chem. Eur. J. 67/2017) [PDF]

, 2017
Association of photoswitch within curcubit[7]‐ and ‐[8]uril tunes the kinetics of the thermal isomerization from VHF‐to‐DHA in the photoswitch. The sun setting through the rolling wave symbolizes the aqueous medium in which the photoswitching processes ...

The role of alkyl substituents in deazaadenine-based diarylethene photoswitches

Beilstein Journal of Organic Chemistry, 2016
Diarylethenes are an important class of reversible photoswitches and often claimed to require two alkyl substituents at the carbon atoms between which the bond is formed or broken in the electrocyclic rearrangement.

Computational Methodology Study of the Optical and Thermochemical Properties of a Molecular Photoswitch

, 2015
We assess how the utilization of different DFT functionals for obtaining the equilibrium geometries and vibrational frequencies affect the description of the thermochemistry and subsequent calculation of the optical properties of a dihydroazulene ...

Crossing the Threshold: Using Photostationary States to Control Supramolecular Polymerisation

Angewandte Chemie International Edition, EarlyView.
Intermediate photostationary states regulate the concentration of a polymerisation‐active monomer. Once the nucleation threshold is crossed, small wavelength‐dependent changes in isomer composition are amplified into a non‐linear supramolecular assembly response.

A Green-to-Near-Infrared Photoswitch Based on a Blended Subporphyrazine–Dithienylethene System

A subporphyrazine (SubPz)–dithienylethene (DTE) photochromic device with 1o and 1c states, was developed and characterized. In this device, the DTE unit can reversibly switch the SubPz absorbance from green to near-infrared [λmax (o/c) = 527 nm/740 nm ...

Catalysis by a Metastable Photoswitchable Cage

Angewandte Chemie International Edition, EarlyView.
A self‐assembled heteroleptic cage is formed by isomerizing a photoswitchable ligand to its metastable Z‐isomeric form (Z‐1) using green light and combining with a non‐switchable ligand (2) and palladium(II) ions. The metastable [Pd2(Z‐1)2(2)2]4+ cage is an out‐of‐equilibrium self‐assembled catalyst, and can be reversibly assembled and disassembled ...
