Ladderization: A Powerful Strategy for Controlling Supramolecular Helical Ordering, Amplifying Asymmetry, and Emerging and Enhancing Circularly Polarized Luminescence

Small, EarlyView.
π‐Conjugated chiral ladder polymers with enantiopure side groups exhibit helical ordering‐induced circularly polarized luminescence (CPL) in poor solvents and in the film state. Vapor‐annealed films show a particularly strong CPL with glum values of > 0.1. Blending chiral/achiral ladder polymers markedly amplifies the asymmetry in the film.

Unraveling the effect of topological structures of B/N‐doped conjugated macrocycles on spectral properties: A computational study

Smart Molecules, EarlyView.
Herein, we constructed a series of fully B‐doped, fully N‐doped and hybrid B/N‐doped conjugated macrocycles considering three key topological factors. At a fixed ring size, the spectra initially redshift then blueshift with varying B/N ratio, while ring size exhibits negligible impact on spectra.

Assessing the Health Impacts of Contaminants on Green Turtles (Chelonia mydas) Along the Southern Coast of Brazil

Environmental Toxicology, EarlyView.
ABSTRACT Chemical pollutants pose a significant threat to marine ecosystems. Among these contaminants are trace elements and polycyclic aromatic hydrocarbons (PAH). Green turtles can be employed to evaluate the oceans' health due to their coastal habitats and exposure to multiple threats.

Precisely Controlled Electrochemical Phosphonylation: Tailoring π‐Conjugated Polymer Properties for High‐Performance Organic Electrochemical Transistors

Angewandte Chemie, Volume 138, Issue 23, 1 June 2026.
The electrochemical C–H phosphonylation enabled precise control over the degree of functionalization (DOF). Systematic tuning of DOF (0.06–0.16) led to improved µC*, transconductance, and time constant values. This finding demonstrates that moderate functionalization enhances organic electrochemical transistor (OECT) performance, opening new avenues ...
