Organic semiconductors are a key component in today’s growing class of molecular electronics. While many π-conjugated organic semiconductors have been well studied, the application of σ-conjugated oligo- and polysilanes in electronic devices is limited. Here in, we report a class of oligosilane–arene σ, π-hybrid materials that exhibit distinct and enhanced solid-state electronic properties relative to its parent components. The single crystal structures of theses hybrid materials show a unique <i>gauche</i> conformation in the oligosilane backbone. This organization is hypothesized to be favorable for charge transport. Solution deposited crystalline thin-films of the hybrid materials showed record-setting space-charge limited current (SCLC) mobilities measured in any molecular silane till date.
