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⁺.

用六亚甲基四胺掺杂无金属的分子钙钛矿以产生非中心对称缺陷

不含金属的钙钛矿（dabcoH _{2 2}⁺）（NH ₄）Br（d-Br）（dabco：1,4-二氮杂双环[2.2.2]辛烷）掺杂有非中心对称的六亚甲基四胺。掺杂剂在结构上不适合原始的钙钛矿晶格，因此导致晶格中的结构波动，并增加了周围dabcoH ₂^2+中的热运动。
