Copolymers Containing 1-Methyl-2-phenyl-imidazole Moieties as Permanent Dipole Generating Units: Synthesis, Spectroscopic, Electrochemical, and Photovoltaic Properties
(MDPI, 2022)
New donor–acceptor conjugated alternating or random copolymers containing 1-methyl-2-
phenylbenzimidazole and benzothiadiazole (P1), diketopyrrolopyrrole (P4), or both acceptors (P2) are reported. The specific feature of ...
Synthesis and cytotoxic activity of 1,2,3-triazoles derived from 2,3-seco-dihydrobetulin via a click chemistry approach
(Elsevier, 2022)
In search of new cytotoxic derivatives based on the lupane scaffold, the seco-lupane azides were coupled with a number of alkynes under the 1,3-dipolar cycloaddition (CuAAC) conditions to afford 1,2,3-triazoles. Phenylalkynes ...
Modular Nitrogen-Doped Concave Polycyclic Aromatic Hydrocarbons for High-Performance Organic Light-Emitting Diodes with Tunable Emission Mechanisms
(Wiley, 2022)
Although bowl-shaped N-pyrrolic polycyclic aromatic hydrocarbons (PAHs) can achieve excellent electron-donating ability, their application for optoelectronics is hampered by typically low photoluminescence quantum yields ...
Ruthenium Olefin Metathesis Catalysts Bearing a Macrocyclic N-Heterocyclic Carbene Ligand: Improved Stability and Activity
(Wiley, 2022)
Formation of sterically hindered C−C double bonds via catalytic olefin metathesis is considered a very challenging task for Ru catalysts. This limitation led to the development of specialised catalysts bearing sterically ...
From truxenes to heterotruxenes: playing with heteroatoms and the symmetry of molecules
(Royal Society of Chemistry, 2022-03-24)
The truxene molecule is more versatile and widespread than ever imagined. At the end of the last century, this star-shaped structure was recognized mostly in liquid crystals. However, the development of optoelectronics ...
Tandem rigidification and p-extension as a key tool for the development of a narrow linewidth yellow hyperfluorescent OLED system
(Royal Society of Chemistry, 2022)
Hyperfluorescence (HF), a relatively new phenomenon utilizing the transfer of excitons between two luminophores, requires careful pairwise tuning of molecular energy levels and is proposed to be the crucial step towards ...
Inclusion of Pentamidine in Carboxylated Pillar[5]arene: Late Sequential Crystallization and Diversity of Host–Guest Interactions
(American Chemical Society, 2022)
Here we describe the inclusion of the minor-groove binding drug pentamidine in its extended conformation into the macrocyclic cavity of water-soluble carboxylated pillar[5]arene. The artificial host–guest system is manifested ...
Anion Recognition by a Pincer-Type Host Constructed from Two Polyamide Macrocyclic Frameworks Jointed by a Photo-Addressable Azobenzene Switch
(MDPI, 2022)
A sterically crowded light-responsive host 1 was synthetized with a 93% yield by applying a post-functionalization protocol utilizing the double amidation of 4,4′-azodibenzoyl dichloride with a readily available 26-membered ...
Hydrogen-bonded supramolecular assemblies of folic acid with simple hexoses
(Elsevier, 2022)
Simple D-hexoses such as D-glucose, D-mannose, and D-galactose were found to form supramolecular complexes with folic acid (FA) in phosphate-buffered saline solution (PBS, pH 7.4) and in the gas phase. Pterin subunit of ...
Triptycene Derivatives: From Their Synthesis to Their Unique Properties
(MDPI, 2022)
Since the first preparation of triptycene, great progress has been made with respect to its
synthesis and the understanding of its properties. Interest in triptycene-based systems is intense; in
recent years, advances ...
