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 SOC2023The fundamental relation between electrohelicity and molecular optical activity
Electrohelicity arises in molecules such as allene and spiropentadiene when their symmetry is reduced and helical frontier molecular orbitals (MOs) appear. Such molecules are optically active and electrohelicity has been suggested as a possible design prin ...
ROYAL SOC CHEMISTRY2023Visible light activated BINOL-derived chiroptical switches based on boron integrated hydrazone complexes
Chiral optical switches, which use light to control chirality in a reversible manner, offer unique properties and fascinating prospects in the areas of molecular switching and responsive systems, new photochromic materials and molecular data processing and ...
ROYAL SOC CHEMISTRY2022Rational 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 ...
EPFL2022Light-Responsive Oligothiophenes Incorporating Photochromic Torsional Switches
Kevin Sivula, Emilie Baudat, Giuseppe Sforazzini, Augustina Jozeliunaite
We present a quaterthiophene and sexithiophene that can reversibly change their effective pi-conjugation length through photoexcitation. The reported compounds make use of light-responsive molecular actuators consisting of an azobenzene attached to a bithi ...
WILEY-V C H VERLAG GMBH2022Acid-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 ...
