Fluorinated and methylated -benzodipyrrole-based acceptors suppressing charge recombination and minimizing energy loss in organic photovoltaics.

The elimination of the A' unit from -type Y6-derivatives has led to the development of a new class of -benzodipyrrole (-BDP)-based A-DBD-A-type NFAs. In this work, two new A-DBD-A-type NFAs, denoted as CFB and CMB, are designed and synthesized, where electron-withdrawing fluorine atoms and electron-donating methyl groups are substituted on the benzene ring of the -BDP moiety, respectively. CFB exhibits a blue-shifted absorption spectrum, stronger intermolecular interactions, shorter π-π stacking distances, and more ordered 3D intermolecular packing in the neat and blend films, enabling it to effectively suppress charge recombination in the PM6:CFB device showing a higher PCE of 16.

Docosahexaenoic Acid-Infused Core-Shell Fibrous Membranes for Prevention of Epidural Adhesions.

Avoiding epidural adhesion following spinal surgery can reduce clinical discomfort and complications. As the severity of epidural adhesion is positively correlated with the inflammatory response, implanting a fibrous membrane after spinal surgery, which can act as a physical barrier to prevent adhesion formation while simultaneously modulates postoperative inflammation, is a promising approach to meet clinical needs. Toward this end, we fabricated an electrospun core-shell fibrous membrane (CSFM) based on polylactic acid (PLA) and infused the fiber core region with the potent natural anti-inflammatory compound docosahexaenoic acid (DHA).

Recent advances in flexible multifunctional electrochromic devices.

Electrochromism refers to the phenomenon in which certain materials undergo a redox reaction under an applied voltage or current, resulting in reversible changes in their optical properties and color appearance. Electrochromic devices (ECDs) show great potential in smart windows, anti-glare rear-view mirrors and displays due to the advantages of low energy consumption and simple control mechanisms. However, traditional ECDs are unfavorable for wearable and deformable optoelectronics due to the structural rigidity and limited functions.
