High‐performance electro‐optic materials featuring enhanced thermal stability through dual‐donor structural crosslinking engineering

open access: yesSmart Molecules, EarlyView.
A groundbreaking dual‐donor crosslinking strategy was reported to significantly enhance the thermal stability, achieving remarkable EO coefficients (257–301 pm/V), glass transition temperatures (Tg) ranging from 107–187°C, and ultrahigh chromophore densities (3.73–4.26 × 10²⁰ molecules/cm³) with exceptional long‐term stability after 500 h at 85°C ...

Unlocking n‐alk‐1‐ynes conformers: Quantum “trigger finger” versus “stiff joint” conformations

open access: yesSmart Molecules, EarlyView.
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.

Nanoscopic Observation of Structural Changes After First‐Firing Behavior in W/GeTe/W Ovonic Threshold Switches Using AFM Tip–Based Local Biasing

open access: yesSmall Methods, EarlyView.
A local‐biasing system using AFM induces site‐specific threshold switching in Ge0.17Te0.83 films, enabling direct observation of crystalline/amorphous interface formation. First‐principles calculations reveal that this structural change induces Te 5p‐dominated mid‐gap states and electric field‐enhanced charge redistribution.
