Doubling the Length of the Longest Pyrene-Pyrazinoquinoxaline Molecular Nanoribbons


Molecular nanoribbons are a class of atomically-precise nanomaterials for a broad range of applications. An iterative approach that allows doubling the length of the longest pyrene-pyrazinoquinoxaline molecular nanoribbons is described. The largest nanoribbon obtained through this approach-with a 60 linearly-fused ring backbone (14.9 nm) and a 324-atoms core (C276N48)-shows an extremely high molar absorptivity (values up to 1 198 074 M-1 cm(-1)) that also endows it with a high molar fluorescence brightness (8700 M-1 cm(-1)).
