      abstract     = {Hot carriers, inheriting excess kinetic energy from
                      high-energy photons, drive numerous optoelectronic
                      applications reliant on non-equilibrium transport processes.
                      Although extensively studied in inorganic materials, their
                      potential in organic-based systems remains largely
                      unexplored. Here we demonstrate highly mobile hot carriers
                      in crystalline two-dimensional conjugated coordination
                      polymer Cu3BHT (BHT, benzenehexathiol) films. Leveraging a
                      suite of ultrafast spectroscopic and imaging techniques, we
                      map the microscopic charge transport landscape in Cu3BHT
                      films following non-equilibrium photoexcitation across
                      temporal, spatial and frequency domains, revealing two
                      distinct high-mobility transport regimes. In the
                      non-equilibrium regime, hot carriers achieve an ultrahigh
                      mobility of ~2,000 cm2 V–1 s–1, traversing grain
                      boundaries up to ~300 nm within a picosecond. In the
                      quasi-equilibrium regime, free carriers exhibit Drude-type,
                      band-like transport with a remarkable mobility of
                      ~400 cm2 V–1 s–1 and an intrinsic diffusion length
                      exceeding 1 μm. These findings position two-dimensional
                      conjugated coordination polymers as versatile platforms for
                      advancing organic-based hot carrier applications.},
