Pure Organic AIE Nanoscintillator for X‐ray Mediated Type I and Type II Photodynamic Therapy

Advanced Science, 2023
X‐ray induced photodynamic therapy (X‐PDT) circumvents the poor penetration depth of conventional PDT with minimal radio‐resistance generation. However, conventional X‐PDT typically requires inorganic scintillators as energy transducers to excite ...

Towards Ideal Electron‐Transporting Transistor Characteristics in Polymer Semiconductors in Ambient Air

Advanced Electronic Materials, EarlyView.
We report a coexistence of a reliability factor of 90% and high electron mobility of 0.6 cm2 V−1 s−1 in FBDPPV‐based n‐type polymer field‐effect transistors. Efficient electron transport in this rigid, coplanar, distortion‐free polymer that induces high mobility and ideal transistor behaviors is supported by efficient intrachain transport and limited ...
