Self‐Immolative Poly(Benzyl Ether)s: Design Principles and Controlled Depolymerization

Chemistry – A European Journal, EarlyView.
Unzipping to Sustainability: This Concept article explores the thermodynamic design of quinone‐methide (QM)‐based poly(benzyl ether)s (PBEs). It explains how a low ceiling temperature (Tc), QM stability, and an entropic gain drive rapid depolymerization (“unzipping”) of PBEs into monomers.

Transition Metal Compounds as Thermochromic Materials: Classification, Properties, Limitations, and Applications

EcoEnergy, EarlyView.
This review systematically examines how different transition metal compounds—such as binary and multinary metal oxides, halides, sulfides, and salts—exhibit thermochromism based on the d‐electron configurations of their transition metal cations. It focuses on three main mechanisms of thermochromism: phase transition, charge transfer, and bandgap change.

Thermoresponsive Gel Polymer Electrolytes Enabled by Retained Double Bonds for Thermal Shutdown in Lithium‐Ion Batteries

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A smart gel electrolyte with thermal shutdown capability has been proposed enabled by a two‐step cross‐linking strategy, which preserves a high density of unreacted double bonds at room temperature. This strategy brings negligible degradation to room temperature electrochemical performance, while under thermal abuse conditions above 115 °C, the gel ...
