Photoacidity of Indolinospirobenzopyrans in Water
Cristian Pezzato, Cesare Berton
The reversible isomerism of indolinospirobenzopyrans is perhaps among the most studied phenomena in the field of molecular switches. Although they began to gain attention as early as 70 years ago following the seminal work of Hirshberg and Fischer, who wer ...
WILEY-V C H VERLAG GMBH2023Dissecting the photoacidity of spiropyran/merocyanine molecular switches in water.
Photochemistry is a discipline that studies the interaction between light and matter with the scope to induce chemical transformations. The first conjugation between light and chemistry can be dated back to the lifespan of Giacomo Luigi Ciamician, who is c ...
EPFL2023Coupled Rotary and Oscillatory Motion in a Second-Generation Molecular Motor Pd Complex
Molecular machines offer many opportunities for the development of responsive materials and introduce autono-mous motion in molecular systems. While basic molecular switches and motors carry out one type of motion upon being exposed to an external stimulus ...
AMER CHEMICAL SOC2023Controlling DNA nanodevices with light-switchable buffers
Cristian Pezzato, Cesare Berton, Valentin Jean Périllat
Control over synthetic DNA-based nanodevices can be achieved with a variety of physical and chemical stimuli. Actuation with light, however, is as advantageous as difficult to implement without modifying DNA strands with photo-switchable groups. Herein, we ...
ROYAL SOC CHEMISTRY2023Nb, Ta and Hf-The tri-dopant tournament for the enhancement of TiO2 photochromism
TiO2 quantum dot (QD) size nanoparticle colloids have shown tremendous photochromic response. Here we show that the of the photochromic response of TiO2 QDs can be further enhanced by doping. Our synthesis approach allows to reach high nominal doping level ...
ELSEVIER SCIENCE SA2023Rational design of protein switches: applications in synthetic biology and cancer immunotherapy
Synthetic biology aims to engineer cells as miniature biological devices to sense, process, and respond to exogenous stimuli. Protein switches are designed to sense and respond to various molecular queues in a fast and specific manner, which fits the requi ...
EPFL2022Acid-base-induced fac → mer isomerization of luminescent iridium(iii) complexes
Kay Severin, Farzaneh Fadaei Tirani, Albert Ruggi, Anastasia Gitlina, Carolina Luciana Plaice
Luminescent Ir(C^N)3 complexes (C^N = cyclometalated arylpyridine ligand) exist in the form of two stable isomers with distinct photophysical and electrochemical properties: fac and mer. Herein, we show that fac-Ir(C^N)3 complexes can be converted into the ...
