A quest for ideal electric field-driven MX@C70 endohedral fullerene memristors: which MX fits the best?
(Royal Society of Chemistry, 2023)Endohedral fullerenes with a dipolar molecule enclosed in the fullerene cage have great potential in molecular electronics, such as diodes, switches, or molecular memristors. Here, we study a series of model systems based ... -
Modified glucose as a sensor to track the metabolism of individual living endothelial cells - Observation of the 1602 cm-1 band called “Raman spectroscopic signature of life”
(Elsevier, 2023)A relatively new approach to subcellular research is Raman microscopy with the application of sensors called Raman probes. This paper describes the use of the sensitive and specific Raman probe, 3-O-propargyl-D-glucose ... -
Reply to: On the existence of collective interactions reinforcing the metal-ligand bond in organometallic compounds
(Nature Research, 2023)replying to J. Poater et al. Nature Communications https://doi.org/10.1038/s41467-023-39498-y (2023) -
Conformation of the Ester Group Governs the Photophysics of Highly Polarized Benzo[g]coumarins
(American Chemical Society, 2023)Photosensitizers that display “unusual” emission from upper electronically excited states offer possibilities for initiating higher-energy processes than what the governing Kasha’s rule postulates. Achieving conditions for ... -
Novel Method for the Synthesis of Merocyanines: New Photophysical Possibilities for a Known Class of Fluorophores
