Synthesis and Light-Induced Actuation of Photo-Labile 2-Pyridyl-1,2,3-Triazole Ru(bis-bipyridyl) Appended Ferrocene Rotors

Molecules, 2018
To realise useful control over molecular motion in the future an extensive toolbox of both actionable molecules and stimuli-responsive units must be developed.

A Tri-Stimuli-Responsive Shape-Memory Material Using Host-Guest Interactions as Molecular Switches.

Macromolecular rapid communications, 2016
A thermo-, photo- and chemoresponsive shape-memory material is successfully prepared by introducing α-cyclodextrin (αCD) and azobenzene (Azo) into a poly(acrylate acid)/alginate (PAA/Alg) network.

Reversible end-to-end assembly of selectively functionalized gold nanorods by light-responsive arylazopyrazole–cyclodextrin interaction

Beilstein Journal of Organic Chemistry, 2019
We propose a two-step ligand exchange for the selective end-functionalization of gold nanorods (AuNR) by thiolated cyclodextrin (CD) host molecules. As a result of the complete removal of the precursor capping agent cetyltrimethylammonium bromide (CTAB ...

Fluctuating-friction molecular motors [PDF]

, 2001
We show that the correlated stochastic fluctuation of the friction coefficient can give rise to long-range directional motion of a particle undergoing Brownian random walk in a constant periodic energy potential landscape.

“Redox switches” of Fe species on zeolite catalysts: Modulating the acidity and the para-xylene yield from methanol

Carbon Future
Molecular switches are widely studied in optical devices, computer science, DNA sensor systems, and chiral synthesis; however, their use in heterogeneous catalytic processes is rarely reported.

meta-Oligoazobiphenyls – synthesis via site-selective Mills reaction and photochemical properties

Beilstein Journal of Organic Chemistry, 2012
The investigation of multi-photochromic compounds constitutes a great challenge, not only from a synthetic point of view, but also with respect to the analysis of the photochemical properties.

On the bromination of the dihydroazulene/vinylheptafulvene photo-/thermoswitch

Beilstein Journal of Organic Chemistry, 2012
Background: The dihydroazulene (DHA)/vinylheptafulvene (VHF) system (with two cyano groups at C1) functions as a photo-/thermoswitch. Direct ionic bromination of DHA has previously furnished a regioselective route to a 7,8-dibromide, which by elimination

Evaluating the Role of Intermolecular Interactions in pi-conjugated Materials: What can we learn from DFT calculations and Raman Spectroscopy [PDF]

, 2019
For practical applications in sensors, dynamic covalent chemistry and molecular (photochromic) switches, soft conjugated materials can be envisaged as promising functional materials.1 To advance in this research field, deciphering the mechanisms involved
