Advances and Perspectives in Graphene‐Based Quantum Dots Enabled Neuromorphic Devices

Advanced Science, EarlyView.
Graphene‐based QDs are zero‐dimensional carbon nanomaterials with pronounced quantum confinement and tunable electronic structures. Herein, we summarize their synthesis strategies and functionalization methods, and highlight their functional roles and operating mechanisms in devices, as well as recent advances in neuromorphic electronics. We anticipate

Late‐Stage Functionalization of Peptides on the Solid Phase

Angewandte Chemie International Edition, EarlyView.
Peptide modifications are essential to control pharmacodynamic and pharmacokinetic properties of peptide drugs. Consequently, strategies that allow for efficient and rapid incorporation of non‐canonical modifications into peptides in parallel formats are highly sought after.

(SP,SP)-(–)-(E)-1,2-Bis(methylphenylphosphinoyl)ethene

Acta Crystallographica Section E, 2009
The title compound, C16H18O2P2, possesses two stereogenic P atoms and shows a distorted s–cis conformation of each O=P—C=C moiety. This has been suggested on the basis of the stereochemical result of 1,3-dipolar cycloadditions with ...

Monosubstituted N‐Arylhydroxylamine Chemistry: Integrating Contemporary Synthetic Approaches for the Efficient Construction of Diverse Heterocyclic Scaffolds

Chemistry – A European Journal, EarlyView.
Monosubstituted N‐arylhydroxylamines represent a unique subclass of hydroxylamines that act as pivotal intermediates in redox transformations and as versatile platforms for further synthetic transformations. They serve as key building blocks in the synthesis of architecturally complex heterocycles and other valuable organic compounds.

Synthesis and Biological Evaluation of Well‐Defined M6P(n)‐Modified Glycopeptides for Targeted Protein Degradation

Chemistry – A European Journal, EarlyView.
A synthetic methodology has been developed to prepare multifunctional M6P and M6Pn ligands of different valency. The glycopeptides were conjugated to cetuximab and then examined to mediate cellular uptake of fluorescently labeled EGFRvIII. Only cetuximab modified by glycopeptides having 3 or 6 M6P or M6Pn residues demonstrated greater uptake.
