However, their stability is hindered by photoinduced halide segregation, causing phase instability and long-term degradation. In this work, we compare two structural modification strategies: a surface post-treatment to form a 2D/3D bilayer and an additive approach to induce a quasi-2D layer using a 2D spacer ligand (butylammonium iodide (BAI)). The bilayer method passivates interfacial defects and halide vacancies, promoting crystallinity, suppressing ion migration, and enhancing stability. In contrast, quasi-2D domains not only exhibit quantum well-like features and passivation effects, but also cause vertical heterogeneity and hinder charge transport. Photoluminescence (PL) analysis reveals differences in ion redistribution and phase segregation mechanisms. As a result, 2D/3D bilayer devices demonstrate superior phase stability, reduced hysteresis, and enhanced performance (PCE 19.03%) with long-term operational stability (>1700 h at >80% efficiency) and high indoor efficiency (PCE 27% at 1000 lux).

Here, we propose a solution-processed flexible organic thin-film transistor (TFT) pressure sensor based on a freestanding poly(3-hexylthiophene) (P3HT)-fullerene (C₆₀) CT film. The film is prepared by air-water interfacial self-assembly, yielding crystallised centimetre-scale, transferable thin films with retained P3HT molecular ordering and P3HT-C₆₀ CT-related interactions. When used as the active semiconductor layer in a flexible TFT, the film shows p-type transistor behavior with an ON/OFF ratio of approximately 10⁵, a maximum pressure sensitivity of 2.03 kPa^-1, and a response time of about 60 ms. The pressure response is attributed to pressure-induced modulation of molecular packing and donor-acceptor interactions within the freestanding film. These results extend the use of P3HT-C₆₀ beyond conventional photovoltaic applications and demonstrate that interfacial self-assembly can provide freestanding donor-acceptor semiconductor films for flexible, gate-modulated tactile sensing.

To bridge these disconnected areas, this review proposes a bioinspiration-processing-structure-function (BPSF) conceptual framework that establishes a unified design pathway for bioinspired fiber materials and fiber electronics. Guided by this framework, we first summarize the transferable design principles derived from fibrous and non-fibrous biological systems. We then discuss how biomimetic processing strategies translate these biological principles into controllable fiber structures. Building on this processing-structure relationship, we further examine how structural engineering controls load transfer, interfacial coupling, and electromechanical stability, and highlight how these structural advantages enable reliable sensing, actuation, and adaptation in integrated fiber electronic systems. Finally, we discuss the key challenges and opportunities.

All four CQDs exhibited superhydrophobic behaviour, while the CR CQDs demonstrated an exceptionally high water-contact angle (CA) of 172° with extraordinary surface water repellence. TEM analysis revealed clear lattice fringes with a lattice spacing of 0.21 nm, indicating the graphite-like 2D planar structure of the CQDs. The superhydrophobic and fluorescent CQDs were further utilized as an anti-counterfeiting agent to create luminous fingerprints.

Two complementary detection strategies were systematically investigated: ratiometric approach based on luminescence intensity ratio and kinetic approaches exploiting emission decay dynamics. Among the kinetic strategies, a time-gated dual-ion lifetime concept - introduced here for the first time for luminescence manometry - enables pressure readout with record-high relative sensitivity reaching 148.33% GPa^-1 while exhibiting complete immunity to temperature fluctuations. Conversely, temperature sensing is achieved <i>via</i> time-gated single-ion Ni²⁺ luminescence, ensuring high thermometric performance with negligible pressure-induced interference. Importantly, this work study, for the first time, the potential of Ni²⁺ ions for application in near-infrared luminescence manometry.

However, its large A-site FA⁺ cation destabilizes the perovskite lattice, favoring transformation into non-perovskite δ-phases under ambient conditions. To overcome this instability, compositional A-site engineering with Cs⁺, Rb⁺, and MA⁺ has been widely explored, but such α-FAPbI₃ stabilizers inherently alter the bandgap and complicate crystallization dynamics. Here, we report an α-FAPbI₃ stabilizer-free seeded growth strategy that directly incorporates FAPbI₃ seeds (SDs) into the PbI₂ precursor, lowering, in this way, the nucleation barrier and guiding directional crystallization. Multiscale simulations showed that the persistent structural characteristics of the dissolving SDs pertain more to the α-phase thereby promoting growth of the photoactive α-phase while suppressing the formation of the competing photoinactive δ-phase. This approach yields highly crystalline films with compact morphology and markedly reduced surface roughness, as confirmed by SEM, AFM, and XRD analyses. Electroluminescence measurements (EL) and optical-electrical device simulations reveal that the combined effects of enhanced carrier lifetime and improved charge transport suppress non-radiative recombination, translating into a champion PCE of 23.51% (compared to a 15.5% PCE for the SD-free device).

Biominerals provide elegant solutions to this dilemma, such as nacre featuring a \"brick-and-mortar\" structure that exhibits a synergistic interfacial adhesion that combines a soft organic matrix for energy dissipation and stiff mineral bridges for load bearing. Inspired by this, we developed a stiff-yet-elastic organic-inorganic adhesive interface among ceramic particles, achieving the preparation of ceramic composite bulks and their synergistic strengthening and toughening. Specifically, by employing thioctic acid-calcium carbonate (TA-CCO) hybrid molecules as a reactive binder, the <i>in situ</i> polymerization constructs a stiff-yet-elastic adhesive interface, featuring a molecular-scale organic-inorganic bicontinuous network, thereby transforming isotropic, disordered powders into cohesive ceramic composite bulks. This stiff-yet-elastic hybrid adhesive interface simultaneously facilitates load bearing and energy dissipation, significantly strengthening and toughening the resulting bulks. Notably, for platelet-shaped particles capable of forming layered structures, the mechanical reinforcement is further amplified. By this approach, we successfully upcycle industrial solid waste powders (blast furnace slag and fly ash) into ceramic composite bulks that mechanically outperform conventional clay bricks and high-strength concrete, while the dynamic nature of the adhesive interface endows the monoliths with thermoplastic-like recyclability.
