Popis: A series of functionalized triptycene scaffolds has been synthesized using 2-formyltriptycene and 5-(2-triptycenyl)dipyrromethane. Using these two key precursors, mixed condensations with different aromatic aldehydes and aryl-dipyrromethanes gave access to all members of triptycenyl meso-substituted porphyrins (AB3-, A2B2-, A3B-, and A4) and allowed their photophysical and electrochemical characterization. Additionally, the first crystal structure of tetratriptycenylporphyrin is reported. 2-Formyltriptycene was also used for the preparation of two different mono-BODIPY-triptycene compounds, while 2,6,14-triiodotriptycene was used in Suzuki and Sonogashira cross-coupling reactions to obtain three-fold BODIPY-substituted triptycene-dye conjugates. The mono- and tri-BODIPY-substituted triptycene scaffolds exhibit good optical properties in the visible to NIR region indicating the potential use of the triptycene scaffold as the core of multi-dye light-harvesting system
