Enantioselective Access to Trifluoromethylated Spirocyclopropyl Heterocycles

Advanced Science, EarlyView.
We report a rhodium‐catalyzed asymmetric [2+1] spirocyclopropanation of methylene azacycles with trifluoromethyl carbenes in situ derived from fluoroalkyl triftosylhydrazones. ABSTRACT Chiral spirocyclopropyl heterocycles have emerged as privileged three‐dimensional structural motifs in medicinal chemistry.

From Magnetic Fibers to Paper Architectures: A Lightweight Strategy for Robust Low‐Frequency Microwave Absorption

Advanced Science, EarlyView.
A scalable process converts para‐aramid fibers into soft‐magnetic building blocks via micrometer‐thick Fe0.64Ni0.36 (Invar‐type) coatings. Assembled into paper, they form a hierarchical conductive network whose tunable permeability enables thin, lightweight microwave absorption in the low‐frequency (S‐band) regime.

Light‐Controlled Conductive Molecular Wire in an Artificial Lipid Membrane

Advanced Science, EarlyView.
A photochromic azobenzene derivative is shown to produce a unique photoelectric response when embedded in artificial lipid membranes. In its trans state, it forms conductive “molecular wires” that enhance membrane conductivity in the dark. Light‐induced cis isomerization suppresses this effect, showing that short‐chain molecules can modulate membrane ...
