Polarity‐engineered Sn‐Ti cluster photoresists for sub‐10‐nm high‐resolution lithography

Smart Molecules, EarlyView.
Enhancing the polarity of clusters can optimize their patterning performance; inspired by this strategy, we designed polarity‐enhanced Sn‐Ti oxo clusters via ligand engineering. The optimal TS‐3 with exposure‐induced polarity switch achieves 8 nm patterning in lithography and achieves simultaneous improvement in resolution and patterning performance ...

White light emitting molecular logic gates

Smart Molecules, EarlyView.
White light emitting smart molecules with Boolean logic computing ability are surveyed. Abstract White light emitting (WLE) materials are of considerable interest with commercial and societal applications in video displays and lighting devices. A characteristic property of WLE materials is the luminescence profile spanning from 380 to 700 nm.

Highly integrated, alignment healing, and full‐recyclable multifunctional flexible devices based on dynamic covalent bonds

Smart Molecules, EarlyView.
This study addresses stability, repair, and recycling in flexible devices using polymers with identical dynamic bonds but incompatible backbones. This enables robust integration, precise self‐healing, and full recyclability. We demonstrate optoelectronic sensors that, after damage, magnetically self‐assemble and heal upon heating.

Facile one‐step synthesis of efficient hybridized local and charge transfer emitter for ultraviolet electroluminescence with low roll‐off

Smart Molecules, EarlyView.
An effective hybridized local and charge‐transfer emitter D3CZ4F featuring multiple C–H⋯F locking interactions was developed, achieving an outstanding EQE of 8.97%, a small roll‐off, an emission peak at 388 nm, and color coordinates of (0.165, 0.025), respectively.

DFT‐assisted rational design of salan ligands for highly enantioselective Zr–salan‐catalyzed hydroxylation of cyclic β‐keto esters

Smart Molecules, EarlyView.
Guided by DFT calculations, the design of novel C1‐symmetric salan ligands without the involvement of Suzuki coupling was achieved, and the preparation of α‐hydroxy‐β‐ketoesters in 99% yield and 99% ee was realized under low catalyst loading. Abstract In this work, a structurally simple, inexpensive, and readily accessible Zr–salan catalytic system was
