Crystallization-Induced Dynamic Resolution toward the Synthesis of (S)‑7-Amino‑5H,7H‑dibenzo[b,d]‑azepin-6-one: An Important Scaffold for γ‑Secretase Inhibitors

, 2016
An enantioselective synthesis of (S)-7-amino-5H,7H-dibenzo­[b,d]­azepin-6-one (S-1) is described. The key step in the sequence involved crystallization-induced dynamic resolution (CIDR) of compound 7 using Boc-d-phenylalanine as a chiral resolving agent ...

Architected Bio‐Based Iontronic Skin With Dual‐Mode Pressure and Strain Sensing

Advanced Functional Materials, EarlyView.
Bio‐based acrylates in combination with an ionic liquid create 3D‐printed ionogels with compositionally tuneable mechanics and ionic conductivity. Gyroid architectures amplify low‐pressure sensitivity while preserving robust strain sensing, enabling dual‐mode detection of pressure and deformation.

Highly Efficient and Stable Roll‐to‐Roll Coated Perovskite Solar Cells Enabled by Antisolvent Vapor‐Assisted Crystallization

Advanced Functional Materials, EarlyView.
Antisolvent Vapour‐Assisted Crystallization (AVAC) enables controlled perovskite crystallization through precisely metered antisolvent vapour, eliminating liquid antisolvent waste. Compatible with roll‐to‐roll (R2R) slot‐die coating, AVAC produces uniform, pinhole‐free films with enlarged grains, delivering efficiencies of 18.3% for R2R fabricated ...

Thermally Robust Room‐Temperature Interlayer Excitons in a Hybrid van der Waals Heterostructure

Advanced Functional Materials, EarlyView.
We report an optically active interlayer exciton in a hybrid van der Waals (PEA)2PbBr4/MoS2 heterostructure that remains thermally stable up to 400 K. The emission exhibits polarization anisotropy consistent with an out‐of‐plane optical transition‐dipole component and shows lifetime extension indicative of electron–hole separation.
