Research Progress on Blue-Phase Liquid Crystals for Pattern Replication Applications

Abstract

Blue-Phase Liquid Crystals (BPLCs) are considered to be excellent 3D photonic crystals and have attracted a great deal of attention due to their great potential for advanced applications in a wide range of fields including self-assembling tunable photonic crystals and fast-response displays. BPLCs exhibit promise in patterned applications due to their sub-millisecond response time, three-dimensional cubic structure, macroscopic optical isotropy and high contrast ratio. The diversity of patterned applications developed based on BPLCs has attracted much attention. This paper focuses on the latest advances in blue-phase (BP) materials, including applications in patterned microscopy, electric field driving, handwriting driving, optical writing and inkjet printing. The paper concludes with future challenges and opportunities for BP materials, providing important insights into the subsequent development of BP.

A blue phase liquid crystal film based on an interpenetrating network and its sensitive humidity response performance

“…[20][21][22][23][24] Many researchers have explored the BPLC stimulus response. 13,[25][26][27][28][29][30] Hu et al designed a large number of hydrogen bond units and a high proportion of polymerizable monomers to construct a selfassembled three-dimensional nanostructure of BPLCSs and generate independent BPLCSs with humidity-responsive behavior. 31 Yang et al designed a moisture-driven chromogenic photonic polymer coating of a hydrogen-bonded 3D blue-phase liquid crystal network which could achieve a moisture-driven reversible color change in the visible spectrum upon breaking the hydrogen bond and subsequent conversion to a hygrophilic polymer coating.…”

Novel maleic anhydride derivatives: liquid crystalline materials with enhanced mesomorphic and optical characteristics

“…Each liquid crystal assembly that makes up a display pixel is governed by its own electromagnetic field. The field modifies the liquid crystals' orientation, which alters how much light can pass through them and result in the images you see on a screen (Alamro et al, 2021;Gomha et al, 2021;Abdou et al, 2022;Alamro et al, 2022;Chi et al, 2022;Uchida et al, 2022;Wang et al, 2022;Yin et al, 2022;Behera et al, 2023;Ma et al, 2023).…”

Synthesis of Thiophene-Based Derivatives and the Effects of Their Molecular Structure on the Mesomorphic Behavior and Temperature Range of Liquid-Crystalline Blue Phases

“…BP III is amorphous and its symmetry is the same as that of I [5]. Due to their self-assembly nanostructures and exotic electric-optical characteristics, BPs have recently encouraged enormous interest in the development of functional LC materials and the great potential for advanced applications in a wide variety of fields such as displays, light modulators, photonic materials, tunable lasers, and optical communications [6,7]. However, the extremely narrow existing temperature range of BPs is still one of the most crucial obstructions for practical application [8].…”
