In this perspective paper， we explore the potential of MI for intelligent human-interactive functions； we focus on liquid crystal polymers （LCPs）， which are uniquely ideal for both MI and human-interactive applications due to their adaptable stimuli-responsive properties and compliance， respectively. We preface our study by building a framework to categorize MI， underlining the need to modify psychology-based terms due to the disparate mechanisms for biological cognition and material intelligence. Based on our framework， we describe LCP mechanisms and compositing methods for actuation， material memory and learning and forgetting behavior， outlining the journey of an LCP from polymer to MI. We conclude our perspective with an overview of the potential applications for LCPs with MI， accompanied by our recommendations for researchers in the pursuit of futuristic applications； ultimately， we believe the field of MI will generate scientific and social impact that surpasses that of AI.关键词：liquid crystal polymers;materials intelligence;soft robotics;human-interactive functions;material compositing29|6|0发布时间：2025-01-13

Endowing circularly polarized luminescence in liquid crystal composites for desired applications AI导读
“据最新报道，圆偏振发光液晶体系研究取得进展，为信息安全等领域提供新方案。”摘要：Circularly polarized luminescence （CPL） reveals the unique excited-state characteristics of chiral luminescent systems， offering broad interdisciplinary applications. However， current chiral luminescent materials typically suffer from inadequate polarized luminescence performance. Chiral liquid crystals possess a distinctive periodic helical structure that can selectively reflect left- or right-handed circularly polarized light. By combining these with luminescent functional materials， one can achieve CPL systems with high luminescence dissymmetry factors. Consequently， the use of chiral liquid crystals to induce and amplify the circularly polarized luminescence performance of luminescent guests has garnered significant attention. This review discusses the research progress and trends in the realm of CPL liquid crystal systems， systematically summarizing the interactions between chiral liquid crystal matrices and luminescent guests （such as organic dyes， colloidal semiconductor quantum dots， carbon quantum dots， perovskite nanocrystals， and upconversion materials）， and elucidating the structural characteristics and performance of these composite systems. Finally， it explores the extensive application prospects of CPL liquid crystal materials in information security， 3D displays， asymmetric synthesis， circular polarization laser， and biosensing，while also contemplating their future directions and potential applications.关键词：circularly polarized luminescence;chiral liquid crystal;luminescence dissymmetry factor;application of circularly polarized light81|230|0发布时间：2025-01-13

Traditional research has mainly focused on the one-dimensional ordered assembly of liquid crystal molecules， such as in Nematic or Smectic phases. This article reviews the latest progress in the complex assembly and phase behavior of polyphilic liquid crystal molecules. By regulating the degree and mode of microscopic phase separation， a series of assembly modes have been achieved， ranging from two-dimensional honeycomb columnar phases to three-dimensional network structures. The article explores the influence of steric effects and phase separation on the formation mechanisms of assembled structures， such as superlattices and Frank-Kasper phases， while also analyzing the role of fundamental mathematical concepts like minimal surfaces and supramolecular chirality in assembly behavior. Additionally， it systematically discusses the phase transition paths in two-dimensional tiling of liquid crystals， the control mechanisms of three-dimensional network structures， and the supramolecular chirality behavior arising from symmetry breaking. These studies provide new insights into the understanding of complex supramolecular systems in nature and artificial reticular chemistry.关键词：liquid crystal;polyphilic molecules;molecular self-assembly;three-dimensional network structure;supramolecular chirality69|70|0发布时间：2025-01-13
