PDIN, ETL material used to modify and enhance surface morphology

High purity and available online with free worldwide shipping on qualifying orders

N,N'-Bis[3-(dimethylamino)propyl]perylene-3,4,9,10-tetracarboxylic diimide (PDIN), CAS number 117901-97-0, is alcohol soluble with the assistance of acetic acid (2% in volume) and a traditional cathode interface material (CIM), similar to that of PFN.

PDIN can be used as electron transporting layer (ETL) material to effectively modify and enhance surface morphology, resulting in a favourable out-of-plane π–π stacking with associated lamellar orientation. PDIN can also be used as a surface modifier on ZnO when ZnO is used as ETL material for organic electronic devices.

PDIN is not soluble in chlorinated solvents, such as chlorobenzene and chloroform. By using trifluoroethanol as solvent for PDIN in perovskite solar cells, high quality PDIN thin film can be formed onto the perovskite layer and the erosion problem can be overcome by using conventional alcohol solvents such as methanol and ethanol. 

PDIN, also known as DAPER DNA precipitation reagent, has a reputation of precipitating DNAs at extremely low concentrations.
