Lewis Acid‐Triggered Spatiotemporally Controllable Ring Opening in a Classic Rhodamine Featuring Φ = 95% Emission

Small Science, EarlyView.
This work reports a breakthrough in rhodamine activation via an elegant Lewis acid coordination strategy. It induces ring opening in spirolactone rhodamine TMR, generating exceptional fluorescence (quantum yields up to 95%) without destructive modifications or structural modification. The method preserves full photocontrol, reversibility, and real‐time

Advancing Single‐Walled Carbon Nanotubes toward Next‐Generation Electronic Materials: The Critical Roles of Purity and Processability

Small Methods, EarlyView.
Single‐walled carbon nanotubes (SWNTs) are promising for a wide range of applications. In particular, their exceptional electrical conductivity positions them as potential alternatives to traditional metal conductors. This review identifies the key mechanisms governing their conductivity within composites and proposes practical pathways for translating

N‐Heterocyclic Tetrylenes with a 1,1′‐Ferrocenylene Backbone and Bis(2,4,6‐triisopropylphenyl)boryl N‐Substituents

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
Ferrocene‐based N‐heterocyclic tetrylenes [Fe{(η5‐C5H4)NBTrip2}2E](E = GePb; Trip = C6H2‐2,4,6‐iPr3)exhibit long EN and short BN bonds, in agreement with increased electrophilicity due to the ‐M effect of the N‐substituents, whose stericdemand prevents coordination of 4‐(dimethylamino)pyridine (DMAP) to theplumbylene PbII atom, but allows the ...

Combustion Performance of Silicone Rubber Polymer Insulation Material Under Damp‐Heat Ageing Conditions: Molecular Insights Into the Effects of Structural Changes on Macroscopic Properties

High Voltage, EarlyView.
ABSTRACT Silicone rubber (SR), an organic silicon polymer material, is known for its excellent heat resistance and mechanical properties. It is widely used in composite insulators and cable accessory materials. However, the ageing caused by humidity and heat significantly impacts its performance, an issue that cannot be ignored. This paper investigates
