The Van Der Waals bonding of molecular organic semiconductor compounds enables them to be deposited on a variety of substrates at low temperatures and without concern for lattice matching. This property can be leveraged in realizing unique devices on very large and very small scales, with applications in energy harvesting, lighting, sensing and microscopy. I will discuss our advances in demonstrating novel optoelectronic devices on non-planar substrates, focusing on novel solar cells and light emitting diodes deposited on fibers, potentially enabling multifunctional (e.g. load-bearing and energy harvesting) textiles. Timepermitting, I will discuss novel probes that enable highly sensitive surface and optical microscopy with nanoscale resolution.
