Application |
1. VA-Mode High Birefringence Liquid Crystal Dopant：It is a highly fluorinated p-terphenyl derivative with negative dielectric anisotropy and high birefringence. It serves as a high-performance dopant for VA-mode liquid crystal mixtures, providing excellent electro-optic response and wide nematic phase range for advanced display applications. 2.FFS/IPS Display Technology MaterialWidely used in fringe-field switching (FFS) and in-plane switching (IPS) liquid crystal displays. The lateral trifluoro substitution on the terphenyl core provides strong negative dielectric anisotropy, enabling fast response time and high contrast ratio in thin-cell VA and FFS panels. 3.Reactive Mesogen (RM) Synthetic Intermediate：The rigid, linear p-terphenyl core with extended pi-conjugation provides excellent molecular orientation and high optical anisotropy. It is a key building block for synthesizing fluorinated reactive mesogens and advanced liquid crystal materials for next-generation display technologies. |

Q: What is CAS 1047653-92-8?
A: CAS 1047653-92-8 is4-[Difluoro(3,4,5-trifluorophenoxy)methyl]-4′-(trans-4-ethylcyclohexyl)-3,5-difluoro-1,1′-biphenyl, a high-purity fluorinated terphenyl liquid crystal material with negative dielectric anisotropy and high birefringence.
Q: What are the main applications of this material?
A: It is mainly used as a high-performance dopant for VA-mode liquid crystal mixtures, a functional material for FFS/IPS display panels, and a building block for fluorinated reactive mesogens (RM) used in optical retardation films.
Q: What performance advantages does this liquid crystal monomer have?
A: It provides high birefringence (Δn > 0.20), strong negative dielectric anisotropy, low rotational viscosity, and fast electro-optic response, making it ideal for thin-cell VA and FFS displays with reduced motion blur.
Q: How should we store and transport this product?
A: Keep sealed away from light, moisture and high temperature. Transport under normal temperature, avoid long exposure to sunlight.
Case 1: VA-Mode High-Performance Liquid Crystal Mixture Dopant
This product is a key high-birefringence dopant for VA-mode nematic liquid crystal mixtures. With its highly fluorinated p-terphenyl core, it provides strong negative dielectric anisotropy and high optical anisotropy, enabling thinner cell gaps and faster response times. It is widely used in high-resolution VA and FFS display formulations for TVs and monitors.
Case 2: FFS/IPS Advanced Display Panel Material
Applied in fringe-field switching (FFS) and in-plane switching (IPS) display panels. The lateral trifluoro substitution on the terphenyl core ensures excellent negative dielectric anisotropy and low viscosity, delivering high contrast ratio, wide viewing angle, and fast electro-optic response for premium smartphone and tablet displays.
Case 3: Thin-Cell Low Motion Blur LCD Application
Used in thin-cell LCD designs targeting ultra-fast response time and reduced motion blur. The high birefringence of this fluorinated terphenyl allows maintaining the required phase retardation at reduced cell gaps, achieving sub-5ms response times ideal for gaming monitors and VR/AR head-mounted displays.
Case 4: Fluorinated Reactive Mesogen (RM) Intermediate
Serves as a key building block for synthesizing fluorinated reactive mesogens (RM) with p-terphenyl core. The extended pi-conjugation and rigid linear structure provide excellent molecular orientation, enabling preparation of UV-curable anisotropic optical retardation films and phase compensation layers for next-generation OLED and LCD displays.
Case 5: Projection Display and LCoS Liquid Crystal Material
Used in liquid crystal on silicon (LCoS) projection display formulations. The high birefringence and low viscosity of this fluorinated terphenyl compound enable fast response times critical for color-sequential projection systems, meeting the sub-1ms response requirements of micro-display panels in projectors and head-up displays.
