We developed self-assembled hydrogels for their application as photosensitizers for CO2-to-CO reduction photocatalysis. Here, we report on the design and synthesis of ullazine chromophore amphiphiles, a class of nitrogen-doped pi-chromophores. Self-assembly is studied in solution by NMR spectroscopy, cryo-TEM, UV/vis and fluorescence spectroscopy, and is supported by single-crystal X-ray structures. The Self-assembly turned out to be a crucial structural feature for efficient photocatalysis.
