Correlation between Hammett Substituent Constants and Directly Calculated π-Conjugation Strength
, 2016 The results of an energy decomposition analysis of ortho-, meta-, and para-substituted benzylic cations and para-substituted benzylic anions H2C−C6H4Rq (R = H, F, CN, Me, OH, NH2, NO2, CHO, CO2H; q = +, −) are presented and discussed.

Small, EarlyView.A three‐residue peptide bioconjugated onto a carbon nanotube quantum defect turns the near‐infrared emission of quantum defects into a reporter of integrins on intact extracellular vesicles, directly in human plasma. The sensor reveals that healthy fibroblast vesicles carry as much RGD‐binding integrin as cancer‐derived ones, an adhesion‐associated ...

Janus Reactivity of a Mononuclear Non‐Heme Iron(III)‐Peroxo Complex Toward Indole Oxidation
Angewandte Chemie, Volume 138, Issue 43, 19 October 2026.The iron(III)‐peroxo complex [FeIII(O2)(12‐TMC)]+ exhibits bifurcating pathways in indole oxidation. N─H indoles undergo N─H H‐atom abstraction, supported by a KIE of 5.2 for N─H/N–D 2,3‐dimethylindoles, whereas N‐methylindoles react via electrophilic addition of the iron‐peroxo group to the C2–C3 double bond of the indole ring, forming iron ...

Designable Nanozymes for Site‐Selective Amide/Ester Hydrolysis
Small, EarlyView.Enzymes involved in posttranslational modifications of proteins routinely perform site‐selective catalysis, regardless of the intrinsic reactivities of the myriad of functional groups present. Synthetic mimics of these enzymes are created through molecular imprinting, with catalytic groups positioned precisely near the targeted amide or ester bonds ...

Equilibrium constants and protonation site for N-methylbenzenesulfonamides
Beilstein Journal of Organic Chemistry, 2011 The protonation equilibria of four substituted N-methylbenzenesulfonamides, X-MBS: X = 4-MeO (3a), 4-Me (3b), 4-Cl (3c) and 4-NO2 (3d), in aqueous sulfuric acid were studied at 25 °C by UV–vis spectroscopy.
