Abstract
AbstractBy using the same saturated organic cations as structural templates, we synthesized and characterized a series of organic‐inorganic hybrid lead iodides with different structural types, namely as, 1D [(Me)4‐Pipz]Pb2I6 (1), 1D [(Me)4‐Pipz]PbI4 (2) and 2D [(Me)4‐Pipz]2Pb5I14 (3), in different organic solutions. Remarkably, these hybrid lead iodides display tunable broadband light emissions from yellow (578 nm) to red (680 nm) spectral range, which can be ascribed to self‐trapped excitons based on systematic spectroscopy characterizations. This work affords one structural design strategy to realize tunable structural skeletons and broadband low‐energy photoluminescence emissions in hybrid lead iodides.
