In recent years, two-dimensional (2D) hybrid lead halide perovskites based on corner-shared [PbX6] octahedrons have received extensive attention with important potentials in single-component white-light emitting diodes (WLEDs) due to the soft and distorted crystal lattices. However, limited research focused on the one-dimensional (1D) perovskites although they possess similar structural superiorities to achieve this performance. Herein, by using different types of organic amine cations as structural direction reagents, we report one new type of hybrid 1D perovskites of APbCl(3) (A = (DTHPE)(0.5), DMTHP, DBN) based on the same 1D face-shared octahedral [PbCl3](-) chains. Upon UV light excitation, these 1D APbCl(3) perovskites exhibit intrinsic broad-band bluish white-light emissions covering entire visible light spectra with the highest photoluminescence quantum yield (PLQY) of 6.99%, which catches up with the values of previously reported 2D perovskites. Through the systematical studies of time-resolved, temperature-dependent PL emissions, theoretical calculations, and so on, these broad-band light emissions can be ascribed to the radiative transition within conjugated organic cations. The facile assembly process, intrinsic broad-band light emissions, and high PLQYs enable these 1D APbCl(3) perovskites as new types of promising candidates in fabricating single-component WLEDs.
