Thermal‐Stable and High‐Performance Organic Nonlinear Optical Chromophores for Advanced Electro‐Optic Modulators

Advanced Science, EarlyView.
To address the challenge of high electro‐optic (EO) activity and thermal stability, four chromophores (BHG1–BHG4) are designed. These incorporate steric hindrance groups into the aniline donor, significantly raising their glass transition temperatures and enhancing alignment stability. The neat BHG2 film achieves an exceptional EO coefficient of 304 pm

A Novel Co3O4@Co3(HITP)2‐Based Sensor for Low‐Temperatures H2S Detection: Fabrication, Performance, and Preliminary Exploration in Monitoring Pork Spoilage

Advanced Science, EarlyView.
Hybrid Co3O4@Co3(HITP)2‐based chemiresitor was constructed for hydrogen sulfide detection at low‐temperature, which presented excellent sensing performance at room and refrigerant temperature. A proof of concept was conducted by monitoring hydrogen sulfide released from pork spoilage at both temperature using a portable device with a smartphone ...
