Poly(pentacenetetrone) as a High‐capacity Cathode for Sodium Batteries

Advanced Science, EarlyView.
Poly(pentacenetetrone) (PPT) is introduced as a high‐capacity cathode for sodium batteries, offering 314 mAh g⁻¹ at 0.2C with excellent cycling stability. At 2C, it retains 92% capacity after 500 cycles. PPT's high performance and stability address key challenges in sodium battery technology, making it a promising material for next‐generation energy ...

Selective Sorting of Semiconducting C70@Single‐Walled Carbon Nanotube Heterostructures with Narrow Diameter Distribution

Advanced Science, EarlyView.
A precise synthesis of C70 fullerene‐filled SWCNTs (C70@SWCNTs) is achieved through vapor‐phase filling followed by polymer sorting. As the SWCNT diameter increases, C70 molecules first stack in a single chain, and then form unusual configurations, including staggered double chains and double helices.

Squaraine Dyes for Organic Photomultiplication Photodetectors with 220% External Quantum Efficiency at 1240 nm

Advanced Science, EarlyView.
The synthesis of a range of squaraine dyes is reported with maximum absorption in solution above 1100 nm. Near‐infrared sensitive organic photomultiplication photodetectors are developed. Photomultiplication occurs via squaraine hole trap‐induced injection of electrons from the external circuit.
