Despite the rapid progress of hybrid organic-inorganic halide perovskites in optoelectronic applications, their water resistance is still limited because of the interaction of both the organic and inorganic components with water molecules. In this study, a cation engineering protocol to obtain a material with inherent high water resistance by incorporating benzamidinium (BAH) cations into the bismuth halide framework is developed. Analysis of the crystal structure indicates that (BAH)BiI 4 exhibits a molecular 1D perovskitoid structure with an edge-sharing mode and strong noncovalent interactions within the crystal, including I•••I interaction, hydrogen bonding, and π-π stacking between adjacent BAH cations. Such strong noncovalent interactions provide excellent water resistance, with negligible decomposition of crystals during water soaking for two months. The feasibility of the (BAH)BiI 4 crystal for X-ray detection, with a sensitivity as high as 1181.8 µC Gy air −1 cm −2 and a detection limit below 77 nGy air s −1 under 50 V bias is further demonstrated. Such good values are due mainly to efficient charge transport along the π-π stacking between neighboring BAH cations and I•••I interactions between adjacent inorganic chains. These findings provide a new approach to improve the water resistance of perovskite/perovskitoid optoelectronic devices.

“…Protonated histamine cations are interconnected with the inorganic skeleton through N–H···I hydrogen bonds, resulting in the formation of a stable structure (Figure c). As shown in Figure b, these strong hydrogen bond interactions make the shortest distances d I–I between the dimers in both directions of the (001) and (010) crystal faces nearly equal to 4.248 and 4.258 Å, respectively, which are roughly equivalent to those of the 0D MA 3 Bi 2 I 9 ( d I–I ∼ 4.263–4.318 Å). , The small distance between the two dimers is beneficial for carrier transport. − To further investigate the noncovalent interactions in 1 , we performed Hirshfeld surface analysis and created fingerprint plots using Crystal Explorer software. − The Hirshfeld surface can intuitively visualize the strength and type of intermolecular interactions; red, white, and blue areas represent strong, medium-strength, and weak interactions, respectively. Hirshfeld surface map of 1 shows that the crystal surface is mainly composed of red and white areas, indicating a large number of noncovalent interactions of different strengths in the structure (Figure c).…”

Bismuth-based halide perovskites have shown great potential for direct X-ray detection, attributable to their nontoxicity and advantages in detection sensitivity and spatial resolution. However, the practical application of such materials still faces the critical challenge of combining both high sensitivity and low detection limits. Here, we report a new type of zerodimensional (0D) perovskite (HIS)BiI 5 (1, where HIS 2+ = histamine) with high sensitivity and a low detection limit. Structurally, the strong N−H•••I hydrogen bonds between HIS 2+ cations and inorganic frameworks enhance the rigidity of the structure and diminish the intermolecular distance between adjacent inorganic [Bi 2 I 10 ] 4− dimers. By virtue of such structural merits, single crystal 1 exhibits excellent physical properties perpendicular to both the (001) and ( 010) faces. Perpendicular to the (010) face, 1 exhibited a high electrical resistivity (2.31 × 10 11 Ω cm) and a large carrier mobility−lifetime product (μτ) (2.81 × 10 −4 cm 2 V −1 ) under X-ray illumination. Benefiting from these superior physical properties, it demonstrates an excellent X-ray detection capability with a sensitivity of approximately 10 3 μC Gy air −1 cm −2 and a detection limit of 36 nGy air s −1 in both directions perpendicular to the (001) and (010) crystal faces. These results provide a promising candidate material for the development of new, lead-free, high-performance X-ray detectors.

Abstract2D Dion–Jacobson (DJ) perovskites recently have attracted extensive attention for X‐ray detection owing to their structural rigidity and environmental stability. The chemical incorporation of π‐conjugation aromatic spacing cations into DJ phase perovskites will increase the rigidity of cation and electron cloud density between adjacent inorganic slabs, thus facilitating structural rigidity and charge transport. However, it is still a challenge to synthesize high‐quality single crystals of DJ phase perovskite with aromatic spacers for detecting X‐ray applications. Here, a new DJ phase perovskite by introducing π‐conjugated aromatic cation spacer, (4ABA)PbI4 (1, 4ABA = 4‐aminobenzylamine), eliminating the van der Waals gap is designed. High‐quality single crystals of 1 are grown via the facile solution method, exhibiting high resistivity (1.97 × 1011 Ω cm), low trap density (3.36 × 109 cm−3), and large carrier mobility‐lifetime product (1.03 × 10−3 cm2 V−1) under X‐ray illumination. Such remarkable physical characteristics endow single crystal 1 detector with high‐performance X‐ray detection including a high sensitivity of 572 µC Gyair−1cm−2, an ultralow detection limit of 7.50 nGyair s−1 and exceptional radiation stability. The X‐ray detection limit of 1 is over 700 times lower than that of routine medical diagnosis (5500 nGyair s−1), demonstrating potential applications in medical examination.
