Here we report a dynamic\u2010covalent strategy that converts a single perylene diimide aldehyde precursor (PDIOA) into a family of nanotubes through one\u2010pot imine formation with small amines. Combining microscopy, diffraction and DFT analysis, we show that steric congestion at the ortho position programs a helical packing mode that nucleates and propagates tubular architectures. Crucially, the nanotube inner diameter can be predictably \u201cdialled\u201d by the steric demand of the amine: increasing steric bulk progressively contracts the tube cavity. Enantiomeric amines further translate molecular chirality into opposite supramolecular helicities, affording mirror\u2010image helical nanotubes. Moreover, tuning monomer concentration and solvent composition enables uniform double\u2010 and triple\u2010walled nanotubes, demonstrating controllable wall\u2010layer engineering within the same chemical platform. The resulting nanotubes exhibit dimension\u2010dependent photoconductive responses, linking programmable nanoscale structure to optoelectronic function. This work establishes a modular, high\u2010throughput and recyclable route to chiral, multiwalled perylene diimide nanotubes with independently addressable diameter, helicity and wall
