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 ... -
Carboxylated Pillar[5]arene Meets Medicinal Biguanides: Host–Guest Complexes with Alexidine and Phenformin in the Crystal and Solution/Gas Phase
(American Chemical Society, 2023)Here, we discuss crystal and solution/gas-phase complexes of carboxylated pillar[5]arene with two cationic guests, alexidine and phenformin, revealing host–guest and assembly curiosities, the role of hydrogen bonding, and ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
NHC–BIAN–Cu(I)-Catalyzed Friedländer-Type Annulation of 2-Amino-3-(per)fluoroacetylpyridines with Alkynes on Water
(American Chemical Society, 2022)The direct catalytic alkynylation/dehydrative cyclization of 2-amino-3-trifluoroacetyl-pyridines on water was developed for the efficient synthesis of a broad range of fluorinated 1,8-naphthyridines from terminal alkynes. ... -
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 ... -
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 ... -
