"charge flowing through organic semiconductor molecules boosted by dopant molecules... organic dopants contain electrons in high-energy levels readily released into semiconductor... derivatives of tetraphenyl dipyranylidene dopant, with added nitrogen-based amine groups pushing electrons into molecule's central region, improved stability (no degradation after 2 weeks) at high temperatures... resulting molecule dubbed DP7 added to semiconductors by vacuum deposition...much lower electrical resistance...
