My dream at @Caltech has been to not only do science, but to also make science more accessible and equitable for all. It is my hope that Rising Tide can be a bridge to connect science to first-gen, low-income, and underrepresented students! @CaltechCCE

I’m a little behind on this one, but excited to share the collaborative research of joint graduate student Ryan Ribson on controlling singlet fission with coordination chemistry. His perseverance saw this through.
#ASAP by @RyanGHadt, Theodor Agapie & team @CaltechCCE! Series of ligand-bridged bipentacenes display differential rates/yields of singlet fission as a result of distinct solution-state structures arising from the identity of the coordinated alkali metal.: https://t.co/lkHnmGTBlt
