Polydiacetylenes (PDAs) constitute a family of conjugated amphiphilic polymers that display unique color and fluorescence properties. Described is the hierarchical assembly of micrometer‐sized tubes that comprise a melamine‐substituted PDA derivative. The nano‐ to microscale transformations of the amphiphilic building blocks were induced by addition of divalent metal ions. The PDA microtubes facilitated the high‐sensitivity fluorescence detection of bacteria.
