Metal-organic frameworks (MOFs) are a diverse class of highly ordered and tunable nanoscale architectures that are increasingly employed in several solar energy conversion schemes. Investigation of light-harvesting and energy transfer processes within the three-dimensional frameworks has demonstrated efficient, long-range energy transfer, akin to natural photosynthetic pigment arrays. The Morris group has pioneered studies in the exploration of energy transfer mechanisms and the role three-dimensional alignment plays in the observed results. Herein, we discuss a new metal-organic framework architecture that exhibits incredibly efficient energy transfer over long distances. The structure optimizes the chromophore spacing and orientation in a way to promote field leading values. The energy transfer efficiency was monitored via both external and internal quenching and transient spectroscopic measurements.
