Electro-optical characteristics of polymer-dispersed liquid crystal containing copper (II) phthalocyanine as a function of UV irradiation time

Preparation of Progressive Driving Bilayer Polymer-Dispersed Liquid Crystals Possessing a PDLC-PVA-PDLC Structure

“…Without voltage being applied, the PDLC exhibits an opaque state due to the random orientation of the LC microdroplets in the polymer substrate [ 2 ]. As a large voltage is applied, the PDLC film appears in a transparent state with high transmittance due to the alignment of the LC microdroplets along the direction of the electric field [ 3 ]. Inspired by the application of PDLC in the display field, these materials have been rapidly developed in recent years.…”

Balanced electro-optical properties and off-axis haze performance of a polymer-dispersed liquid crystal film via refractive index matching

“…[3][4][5][6][7][8][9][10] Among the smart materials, liquid crystal/polymer composites exhibit great potential in the field of intelligent glass and are gradually becoming the materials of choice in green buildings because they combine the stimulation-response characteristics of liquid crystals with the excellent mechanical and easy-processing properties of polymers. [11][12][13][14][15][16] According to their microstructure, current liquid crystal/ polymer composite systems can be classified into several categories: polymer-dispersed liquid crystals (PDLCs), polymer-stabilized liquid crystals (PSLCs), polymer-dispersed and -stabilized liquid crystals (PD&SLCs), polymer microsphere-filled liquid crystals (PFLCs), and polymer wall-stabilized liquid crystals (PWSLCs). [17][18][19][20][21][22][23][24][25] Among them, PDLC films have gained considerable attention, and the industrialization of flexible PDLC films has been realized.…”

A smart and visible way to switch the aromaticity of silicon(iv) phthalocyanines

“…1–3 They thus possess unique optical and electronic properties, such as strong absorption in the visible–near infrared region, namely the Q band (>670 nm, ε > 1 × 10 5 M −1 cm −1 ), and high electrical conductivity, which enable them to be used in various fields, including as dyes and pigments, phototherapeutic agents, semi-conductors, non-linear optics, and catalysis. 4–13 These properties are generally tuned by modifying them with peripheral or axial substituents as well as changing central chelated ions. 3,5,14–19 For example, the introduction of electron-donating groups at the peripheral position of macroclycles of Pcs (especially at the α-position) red-shifts the absorption of their Q bands relative to that of unsubstituted Pcs.…”
