Description General description N,N′-Diphenyl-3,4,9,10-perylenedicarboximide (PTCDI-Ph) is an asphaltene based conducting polymer that has an archipelago model. It is a perylene diimide derivative that has a high electron affinity and shows good chemical stability. It can be used as an active layer in the development of organic electronic devices. Application PTCDI-Ph is a conjugating polymer that forms an ultrathin film that can be used in the fabrication of organic field effect transistors (OFETs) for nitrogen dioxide sensor based applications. Packaging 500 mg in glass insert
