A volumetric three-dimensional digital light photoactivatable dye display
Nature Communications, 2017 Despite living in a three-dimensional world, almost all information in our society is conveyed in a two-dimensional format. Here, the authors provide a technique for the generation of spatially accurate and high-resolution three-dimensional images using ...

Photochromic carbazole photoinitiators for precision visible‐light photopolymerization
Polymer International, EarlyView.New carbazole–naphthopyran derivatives were employed as visible‐light‐activated photoinitiators, enabling rapid and localized radical photopolymerization to produce well‐defined thin solid objects within minutes. Abstract Two carbazole derivatives, each incorporating a naphthopyran unit and an aromatic ketone, were synthesized and evaluated as ...

Quantifying Dual‐Color Photopolymerization in Xolography via Raman Spectroscopy
Journal of Polymer Science, EarlyView.A dual‐wavelength Raman spectroscopy workflow is presented for the quantitative assessment of dual‐color photoinitiators. Contrast and efficiency parameters are extracted from in situ curing curves and spatial Raman mapping is used to find inhomogeneities in printed objects.

Using Light-Switching Molecules to Modulate Charge Mobility in a Quantum Dot Array
, 2014 We have studied the electron hopping in a two-CdSe quantum dot system linked by an azobenzene-derived light-switching molecule. This system can be considered as a prototype of a QD supercrystal.

Smart Molecules, EarlyView.Light‐induced proton release from spiropyran can disrupt the stability of both nanoparticles and endosomal membranes, thereby promoting endosomal escape and ultimately enhancing transfection performance. Abstract Messenger RNA (mRNA) therapy has been explored as a treatment for various genetic disorders. Significant progress has been made in developing

Potent hemithioindigo-based antimitotics photocontrol the microtubule cytoskeleton in cellulo
Beilstein Journal of Organic Chemistry, 2020 Background: Hemithioindigo is a promising molecular photoswitch that has only recently been applied as a photoswitchable pharmacophore for control over bioactivity in cellulo. Uniquely, in contrast to other photoswitches that have been applied to biology,

The photoswitchable ABAMIs for the future regulation of GWT1 in a spatiotemporal level
Smart Molecules, EarlyView.The GWT1‐targeted azobenzene‐aminopyridine derivatives (ABAMIs), sensitive to the light at wavelengths from 365 to 520 nm, are separately developed as photochromic ligands to regulate bioactivity as well as the GWT1 functions. These molecules are smart tools in photopharmacological studies, giving an innovative method for understanding functional GWT1 ...

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.
