Abstract: Effectiveness of molecular-based light harvesting relies on transport of excitons to charge-transfer sites. Measuring exciton migration, however, has been challenging because of the mismatch between nanoscale migration lengths and the diffraction limit. Instead of using… read more here.

Abstract: The guanine derivative, 5‐aza‐7‐deazaguanine (5N7CG) has recently been proposed as one of four unnatural bases, termed Hachimoji (8‐letter) to expand the genetic code. We apply steady‐state and time‐resolved spectroscopy to investigate its electronic relaxation mechanism… read more here.
