• Supramolecular electronics exploits the distinctive features stemming from noncovalent interactions, guiding the self‐assembly of molecules to craft materials endowed with customized electronic functionalities. Hydrogen‐bonded materials, characterized by their capacity to establish dynamic and stable networks, introduce an extra dimension to the development of supramolecular electronic systems. This study presents a comparative analysis of two remarkably small semiconductors utilizing diketopyrrolopyrrole functionalized with urea units as hydrogen‐bonding motifs, strategically positioned at opposing ends of the conjugated core. We show how the subtle distinction in functionalization not only influences morphology and self‐assembly dynamics via hydrogen‐bonding and π‐π stacking formation, but also holds significant consequences for ultimate charge transport properties. Our observations into the interplay of noncovalent interactions provide valuable insights and strategic pathways for the design of novel materials with enhanced electronic characteristics. We explore the synthesis, self‐assembly and charge transport properties of two urea‐containing single core thiophene‐capped diketopyrrolopyrrole derivatives. The subtle differences in molecular design dictate the superior electronic properties of the lactam‐functionalized analogue
