Novel self-assembly of resonant J-aggregates on carbon nanotubes with advanced features and high potential for versatile practical applications is discovered recently. Last decade, the nanoscale devices become much closer to industrial applications due to the progress made in the areas of high-precision instrumentation and nanotechnology.

Natural self-assembly of molecules for creation and/or improvement of such nanoscale devices enables controlled and simple fabrication techniques for the future innovations. Self-assembly of individual molecules into complex J-aggregates, where molecules are well ordered into long 'staircase' shape, has a unique property due to a coupling of the molecules. The coupling facilitates strong coherent resonance of delocalized charge carriers (called excitons) inside such self-assemblies, and such excitons can easily move inside the J-aggregates. Furthermore, coherent coupling between J-aggregates and other nanomaterials provides opportunity to extend such resonant delocalization empowering development of advanced applications in nanoscale photonics and optoelectronics.
