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 ...
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 ...
Carboxylated Pillar[6]arene Emulates Pillar[5]arene in the Host–Guest Crystal Complexes and Shows Conformational Flexibility in the Solution/Gas Phase
(American Chemical Society, 2023)
Despite the thriving interest in the aqueous complexation properties of carboxylated pillar[6]arene, its solid state supramolecular chemistry has remained a mystery. Here, overcoming challenging crystallogenesis, we report ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
