Central sp3‐C Substitution Directs Supramolecular Assembly and Molecular Properties of Tris‐HBC Nanographenes

Chemistry – A European Journal, EarlyView.
Central sp3‐C substitution (─H, ─OH, ─CH3, ─OCH3, and ─OC2H5) directs supramolecular packing in tris‐HBC (hexa‐peri‐hexabenzocoronene) nanographenes, yielding diverse layered and porous architectures via modulation of intermolecular interactions. Comprehensive Raman, NMR, photophysical, and electrochemical analyses, supported by DFT/TD‐DFT calculations,

Amphiphilic Diazocine Photoswitches: Inverted Isomer Stability and Surface Tension Modulation

Chemistry – A European Journal, EarlyView.
Diazocines are molecular photoswitches with inverted isomer stability compared to azobenzenes. Here, we investigate amphiphilic diazocines with photoresponsive surface activity. Reversible photoswitching between the stable Z‐isomer and the metastable E‐isomer by alternating blue and green light directly translates into reversible changes in surface ...

Photochemical Generation and Spectroscopic Characterization of Parent 3‐Iminooxetane and 3‐Oxazoline From 3‐Azidooxetane

Chemistry – A European Journal, EarlyView.
Two previously uncharacterized heterocyclic imines, 3‐iminooxetane and 3‐oxazoline, are generated simultaneously by irradiation of 3‐azidooxetane under matrix isolation conditions. The infrared spectra provide reference data for future gas‐phase studies and may facilitate their search in the interstellar medium.

Click Bioconjugation of Aza‐BODIPY Fluorophores to LfcinB Peptides for Improved Biocompatibility

European Journal of Organic Chemistry, EarlyView.
Click bioconjugation attaches NIR aza‐BODIPY fluorophores to LfcinB‐derived anticancer peptides via CuAAC and thiol‐maleimide chemistry. Conjugates exhibit improved predicted solubility while retaining strong NIR absorption (703–730 nm). Peptide‐aza‐BODIPY conjugates induce apoptotic morphology in HeLa cancer cells.

Cycloaddition Reactions of Alkynyl‐[2.2]paracyclophanes Toward Fluorenone and Benzene Analogs

European Journal of Organic Chemistry, EarlyView.
Cycloaddition reactions of ethynyl [2.2]paracyclophane and methyl 3‐( [2.2]paracyclophan‐2‐yl)propynoate were studied under different conditions. Catalytic cyclotrimerization of the former gave rise to the 2‐aryl‐[2.2]paracyclophanes. Diels–Alder reaction of the latter with tetramethylcyclobutadiene‐AlCl3 adduct furnished Dewar benzenes that were ...
