Usage

General Description

4-N-BUTYLOXYBIPHENYL is a chemical compound with the molecular formula C16H20O. It is a white to off-white powder that is insoluble in water but soluble in organic solvents. This chemical is commonly used as a liquid crystal material in display technology, such as in liquid crystal displays (LCDs) and liquid crystal on silicon (LCoS) devices. It is also used as a heat transfer fluid, a plasticizer in polymers, and a component in some specialized lubricants. 4-N-BUTYLOXYBIPHENYL is considered to have low toxicity, but exposure to high levels should be avoided as it may cause irritation to the skin, eyes, and respiratory system.

An efficient, facile, and fast synthesis of 4-alkoxy-4′-hydroxybiphenyls

A simple, fast and efficient method of synthesis of 4-alkoxy-4′-hydroxybiphenyls has been described. The reactions of 4,4′-dihydroxybiphenyl with appropriate alkyl halides were carried out over 3 h in DMSO in presence of solid powdered KOH.

Influence of main-chain and molecular weight on the phase behaviors of side-chain liquid crystalline polymers without the spacer

A series of end-on side-chain liquid crystalline polymers (SCLCPs) based on a biphenyl mesogen, poly(4,4′-alkoxybiphenyl acrylate) (PBiA-m, m = 1, 4, 6, 10, 18), were successfully synthesized by free radical polymerization or reversible addition fragmentation chain transfer (RAFT) polymerization. The chemical structures of the monomers were confirmed by 1H NMR and mass spectrometry. The phase structures and transition behaviors were studied using DSC, POM and 1D WAXD. The experimental results found that PBiA-m showed the bilayer smectic phase and a higher clearing point (Ti) compared with poly(4,4′-alkoxybiphenyl methacrylate) (PBiMA-m). In addition, poly(4,4′-hexyloxybiphenyl methacrylate) (PBiMA-6) and poly(4,4′-hexyloxybiphenyl acrylate) (PBiA-6) with different molecular weights (Mn) and low molecular weight distributions have been successfully synthesized via the RAFT polymerization. The results indicated that all the polymers exhibited a bilayer smectic phase and Ti increased as the Mn of PBiMA-6 and PBiA-6 increased. Moreover, PBiA-6 had a higher Ti compared with PBiMA-6 with a similar Mn value. All the results suggested that the main-chain (acrylate and methacrylate) and Mn had a great influence on the properties of SCLCPs without the spacer.

Preparation and characterization of side-chain liquid crystal polymer/paraffin composites as form-stable phase change materials

A series of side-chain liquid crystal polymers (SCLCPs), named poly[ω-(4′-n-alkyloxybiphenyl-4-oxy) hexyl methacrylates] (P6biCm, m = 1, 2, 4, 6, 8, 10, 12, 14, 16 and 18), have been synthesized. Novel SCLCP/paraffin composite form-stable phase change materials (FSPCMs) were prepared by introducing P6biCm into paraffin. The minimum gelation concentration (MGC) and gel-to-sol transition temperature (TGS) properties were tested by a tube-testing method . It was found that P6biCm (m = 1, 2, 4, 6, 8, 10) were insoluble in paraffin, while P6biCm (m = 12, 14, 16, 18) exhibited a low MGC (≤6 wt%) and high TGS (TGS of P6biC12/paraffin is 140 °C). The structure and morphology of FSPCMs were systematically investigated by FT-IR, POM, 1D WXAD and SEM. The experimental results revealed that paraffin was restricted in the three-dimensional P6biCm network, leading to the FSPCM without leakage even above its melting point. The thermal properties were studied by DSC and TG. The research showed that the P6biCm/paraffin exhibited excellent thermal stability and high heat storage density. The shape stability was assessed by rheological measurements, indicating that solid hard gel soft gel liquid was observed with the increase of temperature. This work is useful in comprehending the physical mechanism of shape stability and in the meanwhile provides a novel method for synthesis of FSPCMs.

Gel for liquid organic matter, and preparation method and application thereof

The invention discloses a gel for a liquid organic matter, and a preparation method and application thereof. The gel is obtained by introducing a perfluoroalkyl group onto a 4,4'-biphenol skeleton. The gel can solidify the liquid organic matter through a heating-cooling method; moreover, under the action of a cosolvent, a liquid with pungent odour can be solidified quickly; the volatility of the liquid organic matter is reduced.
