| 摘要 |
The invention relates to an n-dopant for doping organic electron transport materials, wherein the n-dopant comprises at least one proazaphosphatrane compound having a three times N-substituted phosphorous atom according to formula 1, wherein R1 - R3 are selected independently from each other from the group R comprising H, D, C1-C60 saturated or unsaturated alkyl, cycloalkyl, heteroalkyl, heterocycloalkyl, C1-C60 aryl, alkylaryl, heteroaryl, ether, ester and PR'3, wherein the group R' comprises substitutes of the group R without PR'3, wherein R1 - R3can be bridged independently from each other; X1 -X3 are selected independently from each other from the group comprising a compound and substituted or non-substituted C1-C10 alkyl, cycloalkyl, aryl and alkylaryl. |
