Abstract Multifunctional polymer materials are extensively applied to regulate the crystallization process of perovskite films. However, a comprehensive understanding correlations among spatial structure polymers, modulation, and device performance is still lacking. Here, restricted assembly strategy proposed prepare high‐quality films by systematically studying effect space configurations polymers on modulating cesium lead triiodide (CsPbI 3 ) perovskite. The results confirm importance high backbone coplanar in promoting nucleation, accelerating phase transitions, enhancing crystalline orientation. with not only facilitates formation uniform dense nucleation sites precisely controlling distribution colloidal particles but also enhances crystal orientation through orientational growth induced structure. As result, efficiency CsPbI solar cells increases from 17.84% 20.39%. Additionally, unencapsulated devices show excellent storage operational stability.

Abstract Mixed Br/Cl perovskite nanocrystals (PeNCs) exhibit bright pure‐blue emission benefiting for fulfilling the Rec. 2100 standard. However, phase segregation remains a significant challenge that severely affects stability and spectrum of light‐emitting diodes (PeLEDs). Here, we demonstrate optimization spacing between polydentate functional groups polymer ligands to match surface pattern CsPbBr 1.8 Cl 1.2 PeNCs, resulting in effective synergistic passivation effect improvements PeLED performances. The block alternating copolymers with different inter‐functional group are facilely synthesized as PeNCs. Surprisingly, higher density do not while enable efficient PeNCs high photoluminescence intensity, low non‐radiative recombination rate exciton binding energy. Density theory calculations clearly confirm almost perfect Finally, PeLEDs achieved at 467 nm Commission Internationale de l′Eclairage (CIE) coordinates (0.131, 0.071), external quantum efficiency (9.1 %) record spectral operational stabilities (~80 mins) mixed‐halide PeLEDs. Overall, this study contributes designing promoting development high‐performance stable pure‐color towards display applications.
