... Organic-inorganic hybrid lead halide perovskites have gained significant attention for optoelectronic applications due to their advantageous characteristics, including high absorption efficiency, extended carrier diffusion lengths, and cost-effective fabrication methods [1][2][3][4][5][6][7]. These materials have been successfully integrated into various optoelectronic devices, including solar cells, light-emitting diodes, lasers, and photodetectors [8][9][10][11][12]. Despite these advantages, lead-based halide perovskites suffer from two main drawbacks: high toxicity and intrinsic instability [13][14][15]. ...

... Hence, thiocyanate plays an important role in the phase transition and induced physical properties of hybrid organic-inorganic materials [26][27][28][29][30][31]. One of the current strategies for designing the structure of hybrid organic-inorganic functional phase change materials (PCMs) is to construct a molecular motion system that is capable of order-disorder phase transitions, rotation, and directional motion [32][33][34][35]. According to previous research, the order-disorder phase transition is currently the most used scheme for designing PCMs, where the random movement of organic cations and inorganic anions is the main trigger for the transition. ...

... Organic nitrogen-containing heterocyclic compounds, such as imidazoles and pyridines, have a certain polarity and planar structural rigidity and are prone to motions including dynamic molecular rotations in response to external stimuli [6][7][8][9][10]. Introducing these compounds into the structure of functional materials can be an effective strategy to induce material phase transitions [11][12][13][14][15][16][17]. As a new type of pseudohalogen compound, thiocyanate ligands facilitate the formation of bridged coordination structures in the crystal space. ...

... The P s is about 5.94 μC · cm À 2 , which is much higher than most 18-crown-6-based ferroelectrics (Table 1 and Figure S12). [37][38][39][40][41][42][43][44][45][46][47][48] The ferroelectric domain structure is another essential evidence of ferroelectricity and can be determined by piezoresponse force microscopy (PFM) based on the thin crystal samples. The amplitude and phase parameters of the PFM images represent the local piezoelectric response intensity and polarization direction, respectively. ...

In this section, the synthesis strategies of chiral ligands is summarized, starting with the most commonly used and commercially available ones, followed by novel ligands, such as the axially chiral molecules. Figure 7 shows several commonly used chiral organic ligands, which of those containing alkyl chains are shown in figure 7(a) [92][93][94], cyclic molecules in figure 7(b) [95][96][97] and substituted aromatic ring in figure 7(c) [98][99][100][101][102][103]. Among these, the most widely used one is α-methylbenzylamine (MBA) due to its commercial availability. ...

... The 1D structure, influenced by the linking mode of inorganic anions, exhibits pronounced local electronic states because of the strong quantum confinement effect, resulting in a wider band gap and greater exciton binding energy [3]. This quantum confinement enhances the material's photophysical properties, leading to broadband emission with significant Stokes shift, attributed to self-trapped exciton states [23]. Additionally, 1D metal halogenides demonstrate improved moisture stability compared to their 3D analogs, which is crucial for applications in perovskite solar cells [24]. ...
