<jats:title>Abstract</jats:title><jats:p>Inorganic semiconductor ferroelectrics such as BiFeO<jats:sub>3</jats:sub> have shown great potential in photovoltaic and other applications. Currently, semiconducting properties and the corresponding application in optoelectronic devices of hybrid organo-plumbate or stannate are a hot topic of academic research; more and more of such hybrids have been synthesized. Structurally, these hybrids are suitable for exploration of ferroelectricity. Therefore, the design of molecular ferroelectric semiconductors based on these hybrids provides a possibility to obtain new or high-performance semiconductor ferroelectrics. Here we investigated Pb-layered perovskites, and found the layer perovskite (benzylammonium)<jats:sub>2</jats:sub>PbCl<jats:sub>4</jats:sub> is ferroelectric with semiconducting behaviours. It has a larger ferroelectric spontaneous polarization <jats:italic>P</jats:italic><jats:sub>s</jats:sub>=13 μC cm<jats:sup>−2</jats:sup> and a higher Curie temperature <jats:italic>T</jats:italic><jats:sub>c</jats:sub>=438 K with a band gap of 3.65 eV. This finding throws light on the new properties of the hybrid organo-plumbate or stannate compounds and provides a new way to develop new semiconductor ferroelectrics.</jats:p>
