Abstract

The invention relates to organic molecules having a structure of formula 1 AF1-(Separator)m-AF2   Formula 1 wherein: m is 0 or 1; AF1 is a first chemical entity, having a conjugated system, in particular at least six conjugated electrons (e.g., in the form of at least one aromatic system); AF2 is a second chemical entity, having a conjugated system, in particular at least six conjugated π electrons (e.g., in the form of at least one aromatic system); with AF1≠AF2; wherein AF1 has a structure of formula 2-1: wherein FG is selected from the group consisting of CR**2F, CF3, CF2R**, SF5, N—(CF3)1, N—(CF3)2, O—CF3, S—CF3 and CF2CO2R*; n=1 to 5; o=1 to 5; n+o=5; p=0 or 1; R′=linking point on the separator, linking point on the chemical entity AF2 or a radical R*; wherein one R′ represents a linking point on the separator or on the chemical entity AF2.
