Open AccessSelf-assembly of luminescent twisted fibers based on achiral quinacridone derivatives
It is a great challenge to spontaneously assemble achiral molecules into twisted nanostructures in the absence of chiral substances. Here we show that two achiral centrosymmetric quinacridone (QA) derivatives, N,...

Droplets of cellulose nanocrystal suspensions on drying give iridescent 3-D “coffee-stain” rings
Films prepared from aqueous suspensions of cellulose nanocrystals (CNC) often display iridescent colors due to the reflection of light from the helicoidal orientation of the rod-like CNC in the film. Droplets ...

Photo-induced iodination of aryl halides under very mild conditions
Aryl iodides are useful precursors in the synthesis of compounds used, for example, in the pharmaceutical and electronics industries. This protocol describes a transition metal–free, photo-induced aromatic Fin...

Visible-light-driven non-oxidative dehydrogenation of alkanes at ambient conditions
Direct non-oxidative dehydrogenation of alkanes produces useful carbon feedstocks and hydrogen fuel. However, breaking the C–H bonds in alkanes typically requires high temperature, stoichiometric oxidants or h...
