Patent ID: 8716510

Claim:
A method for emitting or absorbing light in the spectral range from 400 nm to 500 nm (blue light) in an organic-electronic device, comprising the step of providing a platinum-dicyano-bisisocyanide complex of formula I: wherein (a) R1, R3=each independently H or a branched or unbranched aliphatic or heteroaliphatic group C n H 2n+1 X o with 1≦n+o≦15, and R2=a branched or unbranched aliphatic or heteroaliphatic group C n H 2n+1 X o with 2≦n+o≦15 wherein o is an integer of 0, 1, 2, 3, or 4, or (b) R1=CH 3 and R2, R3=each independently H or a branched or unbranched aliphatic or heteroaliphatic group C n H 2n+1 X o with 1≦n+o≦15, wherein o is an integer of 0, 1, 2, 3, or 4, and wherein the groups X are not neighboring and each group X individually stands for a hetero group or a heteroatom selected from the group consisting of the following hetero groups or heteroatoms: wherein A1, A2, A3, A4, A5, A6, A7, A8, A9, A10, A11 or A12=H or wherein A1, A2, A3, A4, A5, A6, A7, A8, A9, A10, A11 or A12=an aliphatic group of the formula C m H 2m+1 wherein 1≦m≦10.
