Abstract
Replacing the spacer cations from BA to i-BA decreases the interlayer distance and barrier height in 2D perovskite, resulting the decrease of the degree of anisotropy. The (BA)<sub>2</sub>CsPb<sub>2</sub>Br<sub>7</sub> crystal along the <italic>ab</italic> plane exhibits superior X-ray sensitivity.
