Sustainable Synthesis of 4,7‐Dihydro‐4,7‐ethano‐2H‐isoindoles—Key Building Blocks to Benzoporphyrins
Chemistry – A European Journal, Volume 32, Issue 23, 16 June 2026.A facile and sustainable route to isoindole derivatives—key benzoporphyrin precursors—brings high‐ and low‐symmetry benzoporphyrins closer to practical application. ABSTRACT Benzoporphyrins, π extended porphyrin analogues, exhibit remarkable potential for optoelectronic and theragnostic applications, yet have remained largely confined to fundamental ...

Spin Defects in Hexagonal Boron Nitride as 2D Strain Sensors
Advanced Functional Materials, Volume 36, Issue 36, 4 May 2026.We demonstrate that boron‐vacancy (VB${\rm V}_{\rm B}$) centers in hexagonal boron nitride (hBN) enable quantitative strain sensing with sub‐micrometer resolution. Using this approach under continuously tunable in‐plane stress, we precisely quantify strain‐induced shifts of the E2g${\rm E}_{2{\rm g}}$ Raman mode in multilayer hBN, establishing VB${\rm ...

Intermediate Resistance and Capacitance States in Ge‐Rich GeSbTe Phase‐Change Memory
physica status solidi (RRL) – Rapid Research Letters, Volume 20, Issue 4, April 2026.Intermediate states of Ge‐rich GeSbTe phase‐change (PCM) memory cells are investigated by electrical impedance spectroscopy. Resistance and capacitance are extracted using an equivalent RC model, revealing tunable resistance and SET‐state‐dominated capacitance.

Cathodoluminescence Enhancement Mechanisms in Silica Microspheres
Nanophotonics, Volume 15, Issue 6, 27 March 2026.Microspheres are prototypical optical resonators that affect cathodoluminescence (CL) in their surroundings. By resolving CL spectrally, spatially, and angularly, we disentangle the photon generation, absorption, and radiation mechanisms. We find two regimes: The first is dominated by CL from whispering gallery modes, which emanates exclusively from ...

European Journal of Organic Chemistry, Volume 29, Issue 10, 9 March 2026.A range of synthetic methods for photophysically attractive stable luminescent diradicals have been developed, enabling the preparation of diverse derivatives. Direct substitution of the tris(2,4,6‐trichlorophenyl)methyl radical introduces donor groups to afford acceptor–donor–acceptor luminescent diradicals, while halogenated triarylmethanes are ...
