Origin of Enhanced Efficiency and Reduced Roll‐Off in Organic Light‐Emitting Diodes Based on Pt(II) Complexes

open access: yesAdvanced Science, EarlyView.
Controlled Pt–Pt fine structure in square‐planar Pt(II) complexes governs metal–metal‐to‐ligand charge‐transfer (MMLCT) state formation, exciton dynamics, and organic light‐emitting diode performance. Short Pt–Pt contacts in Pt(fppz)2 enable coherent metal–metal coupling, sub‐microsecond emission and an external quantum efficiency of 29%, whereas ...

A Cascaded DNA Nanocircuit for Multi‐Signal‐Responsive Precision siRNA Delivery in Cancer Therapy

open access: yesAdvanced Science, EarlyView.
A cascaded dual‐AND logic DNA nanocircuit is engineered to respond to three tumor‐specific signals in a sequential manner: extracellular acidic pH, membrane‐overexpressed nucleolin (NCL), and intracellular glutathione (GSH). This programmable system selectively releases siPARP1 in glioblastoma (GBM), effectively silencing PARP1 and reversing TMZ ...
