“…The bandgap values correspond well with the respective colors of the materials, and for 1 , 2 and 5 , the values lie in the region of visible-light responsive semiconductors. The recorded values agree with reported hybrid iodoplumbate materials in the literature [ 8 , 12 , 13 , 22 , 35 , 38 ]. In addition, the absorption peak at ~3.91 eV (317 nm) for the reported materials corresponds to the peak at 3.85 eV (322 nm) for pure 1,10-phenanthroline, which may arise due to intraligand π−π * transitions [ 22 , 35 ].…”

“…The calculated band structure for one orientation of the disordered phenanthroline is shown in Figure S18 . There is a significant discrepancy between the calculated band structure and the experimental data (2.87 eV) obtained via diffuse reflectance spectra, which is likely due to the limitations of semi-local DFT functionals that are known to underestimate calculated band gaps [ 12 , 13 ]. Though the band structures fail to accurately predict the band gap for these structures, the calculations do show that the band structure is impacted by the orientation of the phenanthroline molecule.…”

“…Main group halometallate compounds (HMCs) constitute a class of hybrid materials that have been extensively studied for their high structural diversity and tunable optical properties [ 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 ]. These materials often consist of an inorganic halometallate anion and a charge-balancing organic cation.…”

The solvothermal synthesis, structure determination and optical characterization of five new metastable halometallate compounds, [1,10-phenH][Pb3.5I8] (1), [1,10-phenH2][Pb5I12]·(H2O) (2), [1,10-phen][Pb2I4] (3), [1,10-phen]2[Pb5Br10] (4) and [1,10-phenH][SbI4]·(H2O) (5), are reported. The materials exhibit rich structural diversity and exhibit structural dimensionalities that include 1D chains, 2D sheets and 3D frameworks. The optical spectra of these materials are consistent with bandgaps ranging from 2.70 to 3.44 eV. We show that the optical behavior depends on the structural dimensionality of the reported materials, which are potential candidates for semiconductor applications.

“…20 Previously, by introducing isonicotinic acid ligand into the reaction system, we obtained a structurally interesting layered iodoplumbate, namely, K 2 [Pb(MCP) 4 ]Pb 3 I 10 . 12 As an extension of our previous work, in this paper, we continue to explore whether slight changes in reaction conditions can further result in the formation of novel compounds. Fortunately, we successfully prepared two new iodoplumbate hybrids containing in situ-generated N-methylated isonicotinic acid, namely, title compounds show impressive photoelectric responsive properties, especially the full spectrum light illumination.…”

“…The working electrode was fabricated using a slightly modified method in the literature. 12 First, 5 mg of microcrystal sample was dispersed in a mixed ethanol (475 μL) and Nafion (25 μL, 5% in water and 1-propanol) solution, which was then subjected to ultrasound for 30 min. Next, about 100 μL of the above suspensions was coated onto the preclean ITO glass and then dried naturally.…”

By utilizing in situ-formed MCP ligands (HMCP + = 1-methyl-4-(carboxyl)pyridinium) as decoration agents, two new iodoplumbate hybrids, namely, [Pb(MCP) 2 I]PbI 3 (1) and Cs 2 [Pb-(MCP) 4 ]Pb 3 I 10 (2), have been solvothermally prepared and structurally characterized. Compound 1 features the typical onedimensional (1D) [PbI 3 ] n n− anions, while compound 2 exhibits two-dimensional (2D) [Pb 3 I 10 ] n 4n− slabs perforated with large parallelogram-shaped windows. The intriguing structural characteristic of compounds 1 and 2 is that they contain unique chain-like cations of [Pb(MCP) 2 I] + and [Pb(MCP) 4 ] 2+ , respectively.Interestingly, upon alternate visible-light and full spectrum light irradiation, compounds 1 and 2 show stable and rapid photoelectric switching properties, whose photocurrent densities are comparable or larger than those of many metal halide hybrids. Additionally, their optical properties, Hirshfeld surface analyses, X-ray photoelectron spectra, as well as the theoretical band structures and density of states have also been studied.

The low-dimensional (LD) perovskites are proven to be capable of blocking moisture erosion and thereby improving the photovoltaic device stability. In this review, the low-dimensional (LD) perovskite materials are carefully summarized that are induced by A-position organic substituents, starting from the crystal microstructure and electronic structure of LD (2D, 1D, and 0D) perovskite materials with regulating dimensions, combined with first principles calculation (DFT). By further studying the thermodynamics and dynamics of crystallization nucleation and growth of LD-3D perovskite thin films in the heterojunction region, LD-3D heterojunction perovskite thin films and solar cells with controllable dimensions can be in situ prepared. Various LD-3D perovskite structure photovoltaic devices are systematically summarized, which shows flexible regulation of the energy band structure and carrier transport characteristics, locks the water oxygen corrosion channel with close-fitting conjugated structure, and improves the long-term stability of the LD-3D perovskite solar cells. This review is expected to provide some guidance for the perovskite development and multipurpose use through in depth understanding of the structurally dimensional engineering in perovskite photovoltaics.
