Dibenzo[b,d]thiophene-2,8-diylbis(diphenylphosphine oxide), also known as PPT or DPDT, is an organic semiconductor used in OLEDs, where it serves as a high-triplet-energy host and as an electron-transport and hole-blocking material in phosphorescent and TADF devices. Its electron-withdrawing diphenylphosphoryl groups make the molecule electron-deficient, which supports electron transport, and it is offered in sublimed grade for vacuum-deposited device fabrication. Available with a CAS number of 1019842-99-9, this compound has no signal word assigned. Molekula supplies Dibenzo[b,d]thiophene-2,8-diylbis(diphenylphosphine oxide) from research to bulk quantities with full documentation and ISO 9001:2015 traceability.

This substance is available from Molekula on enquiry. Full specification, Safety Data Sheet and Certificate of Analysis documentation are provided with your quotation once our team confirms the grade and pack size you need.
