We demonstrate that the relative positioning of hydrogen\u2010bonding with respect to a \u03c0\u2010conjugated core enables the modulation of conjugation pathways through controlled intra\u2010 or intermolecular interactions. A series of diketopyrrolopyrrole small molecules bearing amides at defined distances from the conjugated backbone was designed to selectively favor distinct hydrogen\u2010bonding types and strengths. Our combined approach, including density functional theory, vibrational and electronic spectroscopies, electrochemistry, and solid\u2010state characterization, reveals that proximal amide groups favor intramolecular hydrogen\u2010bonding, disrupting backbone planarity and limiting effective \u03c0\u2010conjugation. In contrast, distal amides promote intermolecular hydrogen\u2010bonding, sometimes involving DPP carbonyl groups, leading to extended conjugation pathways and enhanced supramolecular organization in the solid state. This modulation of hydrogen\u2010bond topology and strength results in markedly different charge\u2010carrier dynamics and transport, evidenced by electrodeless photoconductivity measurements and organic field\u2010effect transistors. Overall, this work establishes hydrogen\u2010bond and strength, rather than hydrogen\u2010bonding alone, as key molecular design parameter to modulate conjugation extension and charge transport in hydrogen\u2010bonded semiconductors, providing general insights for designing functional supramolecular electronic materials.<\/jats:p>","DOI":"10.1002\/smsc.70383","type":"journal-article","created":{"date-parts":[[2026,8,17]],"date-time":"2026-08-17T13:57:57Z","timestamp":1786975077000},"source":"Crossref","is-referenced-by-count":0,"title":["Tuning
