1-dicyanomethylene) rhodamine (DCRD) as the electron acceptor/anchoring group, respectively, in combination with a N-annulated perylene electron donor and a quinoxaline auxiliary acceptor were investigated for application in dye-sensitizedsolarcells (DSCs) and dye-sensitized photocatalytic hydrogen production. The results showed that the sensitizer with cyanoacrylic acid (YFT-1) based DSCs showed a higher

The dehydrogenative C–N cross‐coupling of unprotected, secondary anilines through ortho‐N‐carbazolation has been achieved using a Ru catalytic system with O2 as the terminal oxidant. The reactions proceed in an intermolecular fashion, selectively in the ortho position. Implications for the field of organic synthesis are discussed.

The three‐domain cooperative supramolecularpolymerization of 1, together with the lag time in which the monomeric species remains inactive, allows seededsupramolecularpolymerization to be performed. The kinetic experiments demonstrate that only seeds based on the intermediate aggregate are able to propagate the supramolecularpolymerization of 1 from their active sites. The results presented herein
quaterrylenebis(dicarboximide) (1) was synthesized, and it exhibits excellent solubility in common organic solvents, high molar absorptivity, and good stability. Moreover, it absorbs and emits light in the near-IR spectral region with a high fluorescence quantum yield. All these properties qualify it as a promising NIR dye for many applications.
