Recently, much attention has been focused on their strong π-π stacks resulting from the large PDI aromatic core. These PDI stacks have distinct optical properties, and p Se hela listan på omlc.org We report here the preparation and use of perylene diimide derivative (PDI) with NIR absorbance (around 700 nm) as nanoprobes for tracking mesenchymal stromal cells (MSCs) in mice. Employing an in-house synthesized star hyperbranched polymer as a stabilizer is the key to the formation of stable PDI nanoparticles with low toxicity and high uptake by the MSCs. Due to the large conjugation and electron-deficient ability of perylene diimide, PDFC shows strong absorption, suitable energy levels and favorable face-on packing.

Perylene diimides (PDI) are a well-studied class of functional organic dyes, and in recent years, they have been accepted as promising scaffolds for the design of small molecule/polymer-based chromogenic and fluorogenic reaction-based-probes because of their strong absorption combined with high fluorescence quantum yield in organic solvents, low reduction potential, good electron-acceptor properties, and broad color range properties. In the report, two organic π‐conjugated molecules consisting of four perylene diimide (PDI) chromophores each are presented and used as non‐fullerene acceptors in indoor photovoltaic devices. The new materials consist of a dimeric N‐annulated PDI core with single PDIs grafted onto the pyrrolic N‐atom positions of the core. Herein, we used perylene diimide (PDI), naphthalene diimide (NDI), and naphthodithiophene diimide (NDTI) with the same alkyl chains combined with dithienothiophene (DTT) unit to obtain three polymer acceptors PPDI-DTT, PNDI-DTT, and PNDTI-DTT, respectively.
