Tuning Aggregation in Liquid‐Crystalline Squaraine Chromophores

Advanced Science, EarlyView.
A novel squaraine dye (SQ) forming columnar liquid crystal (LC) phase is synthesized, whose aggregate state can be tuned without disturbing the columnar structures. The liquid crystallization not only offers a rich spectrum and tuning method of optical property but also a novel path for the prescriptive functionalization of LC SQ materials.

Updated Insights Into the Mechanism of Salt‐Induced Aggregation‐Based Single‐Molecule Surface‐Enhanced Raman Spectroscopy

Advanced Science, EarlyView.
A salt‐gradient model is proposed to investigate the physical nature and update insights into the single molecule surface‐enhanced Raman spectroscopy (SM‐SERS). The release of Ag+ ions from the Ag NPs and the final formation of precipitate of AgCl with Cl‐ on the surface of the aggregated Ag NPs plays as the active and packaging shell to improve the SM‐

Ultrafast Exciton and Spin Dynamics of Monolayer MoSi2N4 Studied by Non‐Degenerate Pump‐Probe Transient Transmission Spectroscopy

Advanced Science, EarlyView.
The resonant energy of the A and B exciton of the new 2D material, monolayer MoSi2N4, is found to be 2.18 and 2.34 eV, respectively, indicating a spin‐splitting energy of ≈160 meV. Complex and diverse exciton dynamics are observed. The work has a profound influence on the future developments of MoSi2N4‐based optoelectronic devices and the synthesis of ...

Tunable Polariton Rabi Oscillation in Phase‐Changing Perovskite Microcavities

Advanced Science, EarlyView.
This work demonstrated the tunable Rabi oscillation of exciton‐polaritons in MAPbBr3 perovskites due to the emergence of ferroelectricity during the crystallographic phase transition. Both the Rabi oscillation and exciton oscillator strength exhibit an unusual temperature dependence that is related to the emergence of ferroelectricity in the tetragonal
