Thermally Activated Delayed Photoluminescence Enables Visible-to-Ultraviolet B Photon Upconversion from ZnSe-PTA to DTBN

Lei Wang, Qianghui Feng, Shenghui Zhou, Feng Chen et autres

Abstract A ZnSe quantum-dots-based hybrid system with 9-phenanthrenecarboxylic acid (PTA) transmitter and 2,6-di-tert-butylnaphthalene (DTBN) annihilator is constructed, realizing visible-to-ultraviolet B triplet–triplet annihilation photon upconversion (TTA-UC) with an ∼800 meV large anti-Stokes shift, which was previously proved unrealizable due to elevated triplet state …

Controllable and Exceptionally Efficient Spin‐Orbit Charge‐Transfer Intersystem Crossing in Twisted π‐Conjugated Perylene Bisimides for High‐Performance Photochemical Applications

Hui Liang, Shangru Li, Zixiang Zhou, Rongxin Zhang et autres

ABSTRACT Herein, we present a rationally designed heavy‐atom‐free photosensitizer by incorporating spin‐orbit charge‐transfer intersystem crossing (SOCT‐ISC) characteristics into a twisted π‐conjugated perylene bisimide (PBI) framework (FQAOPBI). The compound allows direct excitation of the charge transfer (CT) state, whose energy can be modulated …

Rational Charge‐Transfer Modulation for High‐Performance Narrowband Blue Thermally Activated Delayed Fluorophores

Guo‐Wei Chen, Xin‐Yi Zeng, Yaozu Su, Jianfeng Liu et autres

ABSTRACT Multi‐resonance thermally activated delayed fluorescence (MR‐TADF) emitters are attractive for ultrahigh‐definition organic light‐emitting diode (OLED) displays due to their narrowband emission and high color purity. However, the detrimental trade‐off between electroluminescence efficiency and broadened emission band remains a critical challenge for …

Tailoring the Spin Flipping Process of Multi‐Resonance Thermally Activated Delayed Fluorescence Emitter via Symmetry‐Breaking Interaction for Ultralow‐Power Photopolymerization

Yuntao Liu, Wenbin Chen, Zafar Mahmood, Xitong He et autres

Abstract Multi‐resonance thermally activated delayed fluorescence (MR‐TADF) materials are renowned for their excellent color purity; however, their functional versatility and potential for interdisciplinary integration are constrained by the inherently poor spin‐flipping and intersystem crossing (ISC) efficiencies. Herein, this challenge is overcome through …
