Unprecedented 1,2-Aryl Shift Accompanying Double Alkyne Benzannulation
(Wiley, 2023)
The tandem intramolecular hydroarylation of alkynes accompanied by a 1,2-aryl shift is described. Harnessing the unique electron-rich character of 1,4-dihydropyrrolo[3,2-b]pyrrole scaffold, we demonstrate that the ...
Spectroscopic and Crystallographic Characterization of Two Hydrochloride Cathinones: 1-(4-fluoro-3-methylphenyl)-2-(pyrrolidin-1-yl)pentan-1-one (4-F-3-Me-α-PVP) and N-ethyl-2-amino-1-phenylheptan-1-one (N-ethylheptedrone)
(MDPI, 2023)
In this paper, two cathinone derivatives, 4F-3Me-alfa-PVP and N-ethylheptedrone, seized on the illegal drug market in Poland, were described and characterized by various instrumental analytical methods. The compounds were ...
Selective transformations of friedelanes isolated from cork smoker wash solids
(Elsevier, 2024)
Friedelin (1) and 3-acetoxyfriedel-3-en-2-one (4), commonly known as friedelane triterpenoids, have been isolated from cork smoker wash solids (also known as black wax) on a multi-gram scale. These compounds are valuable ...
The magic of biaryl linkers: the electronic coupling through them defines the propensity for excited-state symmetry breaking in quadrupolar acceptor–donor–acceptor fluorophores
(Royal Society of Chemistry, 2023)
Charge transfer (CT) is key for molecular photonics, governing the optical properties of chromophores comprising electron-rich and electron-deficient components. In hotoexcited dyes with an acceptor–donor–acceptor or ...
Aryl versus Alkyl Redox-Active Diazoacetates ─ Light-Induced C–H Insertion or 1,2-Rearrangement
(American Chemical Society, 2023)
Diazo compounds with redox-active leaving groups are versatile reagents for orthogonal functionalizations, previously utilized in the Rh-catalyzed synthesis of highly substituted cyclopropanes. Photochemical activation of ...
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
(Wiley, 2023)
A new, transformative method for the preparation of rhodols and other merocyanines from readily available tetrafluorohydroxybenzaldehyde and aminophenols has been developed. It is now possible to prepare merocyanines bearing ...
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)
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 ...
Facile Functionalization of Ambipolar, Nitrogen-Doped PAHs toward Highly Efficient TADF OLED Emitters
(American Chemical Society, 2023)
Despite promising optoelectronic features of N-doped polycyclic aromatic hydrocarbons (PAHs), their use as functional materials remains underdeveloped due to their limited post-functionalization. Facing this challenge, a ...
