Advanced Functional Materials, EarlyView.DNA strands are employed both as dynamic linkers and nanoscale templates for the integration of Ag2S nanoparticles on MoS2, which in turn imparted photothermal responsiveness; this feature permits the selective cargo (fluorophore, quantum dots or an enzyme) release from the MoS2 surface in response to local heat induced by light irradiation.

2-(2-Nitrophenyl)-1,3-dioxan-5-ol
Acta Crystallographica Section E, 2009 In the title compound, C10H11NO5, the six-membered 1,3-dioxane ring displays a chair conformation, with the hydroxy and 2-nitrophenyl groups in equatorial positions, which minimizes steric hindrance. In the crystal, molecules are linked into chains along

Steric Hindrance Effect as a Decisive Factor for the Self-Assembly of Metallocages
, 2023 In the past decades, many supramolecular cages with different sizes and shapes have been achieved through coordination-driven self-assembly. However, the strategy of topology adjustment by using a steric hindrance effect has not been fully developed.

From Food to Power: Hydrogel Thermoelectrics for Ingestible Electronics
Advanced Functional Materials, EarlyView.We introduce a fully edible thermoelectric–electrochromic platform that harvests heat from food and converts it into a visible color change. N‐type and p‐type hydrogel thermoelectric generators connected in series power anthocyanin‐based electrochromic displays, demonstrating the feasibility of safe, biodegradable, ingestible systems for on‐food ...

X‐Functionality–Driven Photocatalytic Hydrogen Evolution in 2D 4‐X‐PEA2SnI4 Perovskites
Advanced Functional Materials, EarlyView.We report a water‐based synthesis of 2D 4‐X‐PEA2SnI4 perovskite microcrystals with prominent photocatalytic (PC) activity for H2 production. The synergy between organic functionalization and HI‐derived iodide scavenges holes suppress octahedral distortion, and favor electron accumulation, enabling a PC H2 evolution ∼20 µmol·g−1 and long‐term stability ...

Steric Maps to Evaluate the Role of Steric Hindrance on the IPr NHC Ligand
Procedia Computer Science, 2013 AbstractDensity functional theory (DFT) calculations were used to predict and rationalize the effect of the modification of the structure of the prototype 1,3-bis(2,6-diisopropylphenyl)imidazol-2-ylidene) (IPr) N-heterocyclic carbene (NHC) ligand. The modification consists in the substitution of the methyl groups of ortho isopropyl substituent with ...

Is Fe-catalyzed ortho C–H Arylation of Benzamides Sensitive to Steric Hindrance and Directing Group?
, 2019 The previously reported Fe-catalyzed ortho C–H arylation of benzamides relied on bi- or tridentate amide groups and specific iron ligands and was sensitive to steric hindrance.
