Flexible white thermally activated delayed fluorescence polymer with alkyl spacer and side‐chain encapsulation for efficient solution‐processed white organic light‐emitting diodes

FlexMat, EarlyView.
A “gemstone‐necklace” FASCE strategy synthesizes single‐component white polymers (PTF‐Qx) by alternating rigid TADF units with flexible alkyl chains. The non‐doped rigid device achieves a high EQE of 15.66% with stable white emission (CIE: 0.36, 0.46).

Strategic construction of fluorinated surroundings in NIR‐II‐emissive organic semiconducting agents for amplifying cancer phototheranostics

FlexMat, EarlyView.
The development of conventional phototheranostic nanomedicines suffers from an intrinsic trade‐off between NIR‐II fluorescence emission and phototherapeutic effects, leading to poor overall efficacy. Herein, we propose an innovative fluorination strategy by constructing fluorinated surroundings in NIR‐II‐emissive organic semiconducting agents to ...

Programmable crack dynamics engineering enables flexible strain sensors with high linearity

FlexMat, EarlyView.
First‐decoupling theoretical framework of crack evolution elucidating the control methods, mechanistic insights, and structure‐activity relationships is established. Crack propagation from uncontrollable randomness systematically evolves into spatially ordered states.

In situ coating strategy for flexible all‐perovskite tandem modules: A new path toward high‐efficiency flexible photovoltaics

FlexMat, EarlyView.
A gas‐quenching‐assisted in situ additive strategy (MP‐CW) enables the fabrication of high‐quality wide‐bandgap perovskite films on flexible substrates. By leveraging Cl‐DMSO coordination channels, the approach promotes vertical additive diffusion to remove residual DMSO and passivate buried interfaces. As a result, flexible all‐perovskite tandem solar

Chiral supramolecular electronics for high‐efficiency circularly polarized organic light‐emitting diodes

FlexMat, EarlyView.
This perspective highlights supramolecular strategy for achieving band‐level chirality in vacuum‐deposited triazatruxene thin films, enabling circularly polarized organic light‐emitting diodes (OLEDs) with both high dissymmetry factor and external quantum efficiency, thereby overcoming the longstanding efficiency‐dissymmetry trade‐off in circularly ...

A Deep Learning Framework for Forecasting Medium‐Term Covariance in Multiasset Portfolios

Journal of Forecasting, EarlyView.
ABSTRACT Forecasting the covariance matrix of asset returns is central to portfolio construction, risk management, and asset pricing. However, most existing models struggle at medium‐term horizons, several weeks to months, where shifting market regimes and slower dynamics prevail.
