Organic materials continue to make an impact in a wide variety of optoelectronic applications due to the access to a design space that ranges from the molecular to the mesoscale. The confluence of conformational flexibility, multiscale dynamics, and diversity in molecular design makes organic conjugated systems an exciting materials family for the study of fundamental phenomena as well as applied materials research. In particular, the continued development of conjugated organic systems for electronic applications relies on our increased understanding of the way they interact with photons and how they transport both electronic and ionic charges.

Organic materials are a broad field, and this symposium will emphasize the fundamental processes of light-matter interactions, electronic, ionic, and coupled ionic-electronic transport in conjugated molecular systems. Applications to light harvesting and light emission, electronic devices, sensing, and signal transduction will be highlighted. Attention will be paid to the control and study of phenomena at materials interfaces. This symposium intends to highlight work that bridges the gap between molecular properties and device performance through novel characterization techniques and cross-disciplinary studies.
