Abstract The variation of the structural elements in donor‐acceptor substituted polyenes 1 (A 1 = A 2 = CN, R 1 and R 2 form a cyclohexene or pyrane ring, D is an amino substituted phenyl or thiophene ring) influence very much their thermal, emissive and photo‐electronic properties. The contribution shows that the emission can be varied from 630 nm to almost 714 nm. The performance data in a typical device are given and discussed in detail. The substitution pattern influence the thermal properties of the dyes 1 as well. Just by introduction of F‐atoms in the cyclohexene derivatives the thermal behaviour can be influenced very positively, which is of particular interest for the technical use of the dyes.
