Patent ID: 8460581

Claim:
An electronic or optoelectronic structural element comprising at least one organic matrix compound, and a p-dopant, wherein the p-dopant is an imidazole derivative represented by one of the following formulae: wherein X is selected from the group consisting of substituted and non-substituted conjugated double-bond systems, substituted and non-substituted quinoid aromatic ring systems, substituted and non-substituted quinoid anellated aromatic ring systems, substituted and non-substituted quinoid heteroaromatic ring systems, and substituted and non-substituted quinoid anellated heteroaromatic ring systems; Y is selected from the group consisting of 2-indandione derivatives, C(CN) 2 , NCN, O, 2-cyclopentadiene derivatives, 2-cyclopentenedione derivatives, C(CF 3 ) 2 , C(CN)aryl, C(CN)oligoaryl, C(CN)heteroaryl, C(CF 3 )aryl, C(CF 3 )oligoaryl, C(CF 3 )heteroaryl, N-heteroaryl, N-oligoaryl, acceptor-substituted aryl, and acceptor-substituted heteroaryl; R 1 -R 8 are independently selected from the group consisting of hydrogen, substituted and unsubstituted aryls, substituted and unsubstituted heteroaryls, substituted and substituted conjugated hydrocarbon chains with alternating C—C single and double bonds, halogen, cyano, pseudohalogen, nitro, halogenated or perhalogenated alkyls, carboxylic acids and derivatives thereof, and sulphonic acids and derivatives thereof; wherein at least one of R 1 -R 8 is not hydrogen, or wherein two adjacent R 1 -R 8 are elements of an aromatic ring system anellated to the imidazole ring; and wherein the p-dopant forms a dopant layer arranged on the matrix compound, or wherein the p-dopant and matrix compound form a p-doped layer having a concentration of the p-dopant to the matrix compound of less than 1:2 or more than 2:1.
