Proazaphosphatranes As N-Dopants In Organic Electronics

A method for producing n-conducting organic-electrical layers, the method comprising

• depositing an organic n-dopant together with a matrix material within a layer, wherein the n-dopant comprises at least one proazaphosphatrane compound having a triple N-substituted phosphorus atom of the formula
• wherein R1-R3 are independently selected from the group consisting of H, D, C1-C60 saturated or unsaturated alkyl, cycloalkyl, heteroalkyl, heterocycloalkyl, C1-C60 aryl, alkylaryl, heteroaryl, ethers, esters, and PR′3, wherein the group R′ encompasses the substituents of group R without PR′3, where R1-R3 independently of one another may be bridged;
• X1-X3 are independently selected from the group consisting of a bond and substituted or unsubstituted C1-C10 alkyl, cycloalkyl, aryl, and alkylaryl, and
• the n-dopant and the matrix material are reacted.
