Unlocking n‐alk‐1‐ynes conformers: Quantum “trigger finger” versus “stiff joint” conformations
Quantum chemical analysis reveals the unique function of n‐alk‐1‐yne terminus as a Quantum “Trigger Finger,” exhibiting two near‐isoenergetic conformers (Cs ${\mathrm{C}}_{s}$and C1 ${\mathrm{C}}_{1}$) locked by a symmetric high barrier. This contrasts with the lower asymmetric barrier of the conventional asymmetric “Stiff Joint” alkyl chain.

Herein, we constructed a series of fully B‐doped, fully N‐doped and hybrid B/N‐doped conjugated macrocycles considering three key topological factors. At a fixed ring size, the spectra initially redshift then blueshift with varying B/N ratio, while ring size exhibits negligible impact on spectra.

A novel chemosensing platform based on a molecular rotor architecture is established for specific, dynamic detection of lysosomal viscosity. The platform allows real‐time tracking of lysosomal viscosity fluctuations induced by various chemotherapeutic agents, highlighting its significant potential as a powerful tool for early cancer diagnostics and ...

The expansion of {Pb6} wheels in zeolite‐type MOFs led to emission thermal quenching of 93%, relative sensitivity of 1.03% K−1 (intensity‐based) and 0.97% K−1 (lifetime‐based) in a wide temperature range of 298–423 K. Abstract The development of luminescent thermometers synchronously exhibiting high sensitivity and stability in a wide temperature range

Organotitanyl “TiCp” Fragment Capping the Bowl‐Shaped Unit in the Ternary Anion [(Cp)Ti(Sn3Bi3)]2−
A novel ternary anion, [(η5‐Cp)Ti(Sn3Bi3‐κ3)]2− composed of a cyclopentadienyl titanium fragment coordinated by a Sn3Bi3 bowl‐shaped cluster unit, is reproted. Unlike homoatomic nine‐atom clusters of heavier tetrel elements, which retain their identity upon dissolution, intermetalloid clusters are not formed directly from ternary alkali‐metal alloys in
