"1,8,13-substituted tripodal triptycene assembled into 2D hexagon stacked 1D, creating 2D + 1D structure... sandwiching pentacene and anthracene chromophores in space between, organizing planar acene chromophores, forming 2 distinct 2D self-assembling structures... single high-energy photon converted into 2 lower-energy triplet excitons, enhancing solar cell efficiency by increasing charge carriers... singlet fission occur with 88% quantum yield for generating pair of triplets and 130% for producing 2 free triplets
