Abstract: The metal-free perovskite (dabcoH22+)(NH4)Br (d-Br) (dabco: 1,4-diazabicyclo[2.2.2]octane) was doped with non-centrosymmetric hexamethylenetetramine. The dopant was not structurally adapted to the original perovskite lattice, and thus caused structural fluctuations in the lattice and increased the thermal motion in the surrounding dabcoH22+.
