Great collaboration with the group of Colin Nuckolls where we investigate the special properties of #fluorescent dyads with energetically degenerate redox states. The paper is just out in @chemicalscience.rsc.org: DOI doi.org/10.1039/D5SC...

Fluorescence Friday! New paper in Chemistry – A European Journal. We tune molecular orbitals of acridinium dyes by substitution with electron withdrawing groups to suppress PET quenching, turn on the #fluorescence and gain activity in #photocatalysis.

Packing hundreds of fluorescent molecules in nanoparticles can lead to super bright labels and probes. However, this requires solving the problem of aggregation caused quenching and understanding the photophysics of dyes in materials. See our perspective in Chem Sci.
