Integration of Perylene Diimide into a Covalent Organic Framework for Photocatalytic Oxidation.

Perylene diimides (PDIs) have garnered considerable attention due to their immense potential in photocatalysis. However, manipulating the molecular packing within their aggregates and enhancing the efficiency of photogenerated carrier recombination remain significant challenges. In this study, we demonstrate the incorporation of a PDI unit into a covalent organic framework (COF), named PDI-PDA, by linking an ortho-substituted PDI with p-phenylenediamine (PDA) to control its intermolecular aggregation.

Safranal acts as a neurorestorative agent in rats with cerebral ischemic stroke via upregulating SIRT1.

Safranal is an active ingredient of saffron (.). Its neuroprotective role in ischemic stroke (IS) through reducing oxidative stress damage has been widely reported.
