Based on their optoelectronic properties and solid-state structures, we selected compounds I6, I8a, and I9 to construct organic field-effect transistors (OFETs). These devices were fabricated by drop-casting their solutions onto platinum or pentafluorobenzenethiol (PFBT) functionalized gold-coated platinum structures on SiO₂/Si substrates (details provided in Section S7). Scanning electron microscopy (SEM) images revealed a uniform and continuous distribution of the organic films within the gate channel (Figure ), indicating effective film formation. The films exhibited smooth surfaces without noticeable defects or aggregation. Additionally, energy-dispersive X-ray spectroscopy (EDX) confirmed the electrode morphology by verifying its elemental composition.
