<jats:title>Abstract</jats:title><jats:p>This work describes the design and synthesis of a π‐conjugated telluro[3,2‐<jats:italic>β</jats:italic>][1]‐tellurophene‐based synthon that, embodying pyridyl and haloaryl chalcogen‐bonding acceptors, self‐assembles into nanoribbons through chalcogen bonds. The ribbons π‐stack in a multi‐layered architecture both in single crystals and thin films. Theoretical studies of the electronic states of chalcogen‐bonded material showed the presence of a local charge density between Te and N atoms. OTFT‐based charge transport measurements showed hole‐transport properties for this material. Its integration as a p‐type semiconductor in multi‐layered Cu<jats:sup>I</jats:sup>‐based light‐emitting electrochemical cells (LECs) led to a 10‐fold increase in stability (38 h <jats:italic>vs</jats:italic>. 3 h) compared to single‐layered devices. Finally, using the reference tellurotellurophene congener bearing a C−H group instead of the pyridyl N atom, a herringbone solid‐state assembly is formed without charge transport features, resulting in LECs with poor stabilities (<1 h).</jats:p>
