Still, the spectrum of available 2D MHPs with diammonium spacers remains limited with respect to their monoammonium counterparts. In addition, ditopic cations have been neglected so far in 2D lead-chloride perovskites with respect to their iodide and bromide counterparts. This hinders the comprehension of the role of structural degrees of freedom within the diammonium cations on both the resulting structural motifs (2D or 1D) and the functional properties. Understanding the latter is fundamental prerequisite to design novel and tailored diammonium-based 2D MHPs.
