Perspective of these macromolecules lies in their unique structure tunable towards specific properties. Thus, covalent organic frameworks possess a wide range of applications such as molecular storage and separation, sensing, heterogenous catalysis, electrochemical energy storage or (opto)electronics. Our general research interest is directed towards organic molecules, highly pi-conjugated systems in particular, with perspective optoelectronic properties. In this context, sp2 carbon-conjugated COFs combining extensive pi-electron delocalization due to olefinic connections with high chemical stability are attractive candidates to be investigated. Knoevenagel condensation has been utilized to form olefinic bonds between two monomers, namely 2,2',2''-(benzene-1,3,5-triyl)triacetonitrile or 2,4,6-trimethyl-1,3,5-triazine, and diverse aromatic carbaldehydes. Structural regularity has been achieved by a combination of optimized reaction conditions and solvothermal synthesis. Moreover, oligomers of the designed COFs were synthesized to verify the condensation of building blocks and to properly elucidate structure-property relationships.	benzenetriacetonitrile; trimethyltriazine; covalent organic framework; carbaldehyde; Knoevenagel condensation
