Colloidal quantum dots (QDs) are promising regenerable photoredox catalysts offering broadly tunable redox potentials along with high absorption coefficients. QDs have thus far been examined for various organic transformations, water splitting, and CO2 reduction. Vast opportunities emerge from coupling other homogeneous catalysts, such as transition metal complexes or dyes, into hybrid nanoassemblies exploiting energy transfer (ET), leveraging a large cross-section of long-lived triplet...

Lead halide perovskite quantum dots (LHP QDs) CsPbX3 generate immense interest as narrow-band emitters for displays, lasers, and light sources. All QD applications rely on suited engineering of surface capping ligands. The first generation LHP QDs employed oleic acid/oleyl amine have found only a limited use in photoredox catalysis. These catalysts been reported to be unstable decompose over the course reaction, thus reducing turnover numbers (TONs) limiting their synthetic ability. Herein,...

In this article, we describe the development of a new aerobic C–H oxidation methodology catalyzed by precious metal-free LaMnO3 perovskite catalyst. Molecular oxygen is used as sole oxidant in approach, obviating need for other expensive and/or environmentally hazardous stoichiometric oxidants. The electronic and structural properties catalysts were systematically optimized, reductive pretreatment protocol was proved to be essential acquiring observed high catalytic activities. It...

Lead halide perovskite quantum dots (QDs), the latest generation of colloidal QD family, exhibit outstanding optical properties, which are now exploited as both classical and light sources. Most their rather exceptional properties related to peculiar exciton fine-structure band-edge states, can support unique bright triplet excitons. The degeneracy excitons is lifted with energetic splitting in order millielectronvolts, be resolved by photoluminescence (PL) measurements single QDs at...

In this work, we developed an efficient method for the rapid construction of fluoranthene skeleton to access a variety substituted hydroxyfluoranthenes. The 1-iodo-8-alkynylnaphthalene derivatives, which serve as substrates key fluoranthene-forming step, were prepared via selective monoalkynylative Sonogashira reactions 1,8-diiodonaphthalene. domino reaction sequence involves sequential Suzuki–Miyaura coupling, intramolecular Diels–Alder reaction, and aromatization-driven ring-opening...

Abstract In this article, the presence and effects of polarization‐enhanced hydrogen bonding in 1,8‐dihydroxynaphthalene (1,8‐DHN) were investigated detail through a series experimental computational studies. First, conformation 1,8‐DHN, its ability to make intra‐ intermolecular bonds solid state by X‐ray crystallography, solution NMR spectroscopy, computationally density functional theory. Second, equilibrium binding constants, which determined 31 P‐NMR titration studies, demonstrated...
