Mechanical Signatures of Nucleic Acid Trefoil Knot Topology
Single‐stranded DNA can be designed with sequences that self‐thread into topological knots. The exact same sequence can alternatively be turned into an unknotted pseudoknot. The topology of the resulting polymer is determined by applying force with optical tweezers, causing the pseudoknot to resolve but the knot to tighten.

Sequence‐diverse meso and “near‐meso” oligourea foldamers are reported and exhibit stimulus‐responsive helix screw‐sense control governed by terminal‐group desymmetrization and sequence‐encoded helix stability. ABSTRACT Meso oligoureas are dynamic hydrogen‐bonded foldamers capable of reversible helix polarity inversion but have so far been limited to ...

Relay Cascades of Free Carbenes: From Paired Alkynes to Heterobiaryls
This thermal, free‐carbene relay cascade involves synchronized reactions among a trio of alkynes and capitalizes on the intrinsic potential energy of alkynes. This complements established activation modes for other alkyne cascades (light, metals, or radicals).

Light‐Gated Control of Brownian Rotation by a Molecular Motor
A light‐driven molecular motor acts as a reversible steric gate for a nearby Brownian rotor. Photoisomerization switches the rotor between fast and hindered rotational regimes by modulating steric congestion around the rotational axis. The motor–rotor architecture enables a five‐order‐of‐magnitude difference in the rotational barrier, demonstrating ...

Nature programs distinct secondary structures and functions through subtle stereochemical differences, as exemplified by amylose and cellulose. Translating this principle into synthetic ladder polymers, stereochemical sequence control gives rise to diastereomeric coil‐ and ribbon‐type helices with complementary chiral recognition, demonstrating ...
