讲座摘要：The electronic and physical properties of soft/organic matter/materials are widely tunable and are often determined by their nano-to-mesoscale structure. The complex interplay between structure and these fundamental properties is applicable in a host of technologies and therefore important in many research areas. Unfortunately, such structure is particularly difficult to measure due to the low contrast with many traditional probes (X-rays, neutrons, or electrons) and low levels of molecular ordering. Recent advances in resonant soft X-ray techniques have opened new avenues to explore mesoscale physics in organic materials by probing the unique electronic orbitals in each molecule. I will discuss the work revealing the power of resonant X-rays to investigate complex hierarchical structure and molecular orientation of organic solar cells. With this new capability to look deep inside organic systems, we can now probe origins of emergent properties in functional organic materials, making possible their use in a new class of flexible electronics that could revolutionize how we use technology and embody an abundant and economically competitive source of renewable energy.
