Perovskite solar cells (PSCs) are ideally fabricated entirely via a scalable solution process at low temperatures to realize the promise of simple manufacturing, low-cost processing, compatibility with flexible substrates, and perovskite-based tandem solar cells. However, high-quality photoactive perovskite thin films under those processing conditions is a challenge. Here, a laminar…

Small molecule ladder-type heteroarenes IHBT-2F is designed and synthesized with strong electron-donating and molecular packing properties, where the central unit, fused thienobenzene-thienothiphene (IHBT), is attached with the strong electron-deficient 2-(5,6-difluoro-3-oxo-2,3-dihydro-1H-inden-1-ylidene)malononitrile (2FIC) as the end group. The counterpart IDBT-2F with…

High-performance polyurethane nanocomposites based on UPy-modified cellulose nanocrystals

Tian, Donglin; Wang, Fenfen; Yang, Zhijun; Niu, Xiling; Wu, Qiang; Sun, Pingchuan

Densely H-bonding assemblies are the key strategy found by nature to enhance the rupture strength of natural polymers without sacrificing their toughness, such as spider silk, while it still remains a great challenge using such intriguing strategy to prepare high-performance synthesized polymer or biopolymer enhanced polymer nanocomposites. To address this…
