Usage

General Description

1,4-Bis(10-undecenyloxy)benzene is a chemical compound with the molecular formula C30H48O2. It is a type of bisphenol, which means it contains two hydroxyphenyl groups. 1,4-Bis(10-undecenyloxy)benzene is often used as a building block in the synthesis of liquid crystal compounds and polymers. It has a long hydrocarbon chain, making it hydrophobic and suitable for use in products that require a non-polar environment, such as certain types of plastics, surfactants, and lubricants. Additionally, it has potential applications in the field of nanotechnology and material science due to its unique molecular structure and properties.

Synthesis and characterization of precisely-defined ethylene-co-aryl ether polymers via ADMET polymerization

A new family of polyolefins containing various aryl ether units have been designed and synthesized, and their thermal properties were studied. We prepared six acyclic diene monomers di(undec-10-enyloxy)aryl ether by a two-step approach and the corresponding homopolymers and copolymers with 1,9-decadiene by ADMET. Subsequent hydrogenation gave the corresponding ethylene-co-aryl ether polymers. The structures of these polymers were confirmed by 1H NMR, 13C NMR and FT-IR. Additionally, crystallization behaviors and thermal properties were investigated by differential scanning calorimetry (DSC), X-ray diffraction and thermal gravimetric analysis (TGA). The results show that incorporation of these aryl ether units has improved the thermal stability of polymers. And these polymers show a tendency of semicrystallinity to amorphous state with the insertion of more rigid phenyl rings in functional sites of polymers' main chain. Interestingly, DSC analysis reveals that a sequence of melting/crystallization phenomenon occurs in the crystalline saturated homopolymers.

Side-chain polysiloxane liquid crystalline elastomers from non-mesogenic components

Synthesis and characterisation of two new azo-based polysiloxane elastomers containing non-mesogenic monomers and different cross-linkers are described. The chemical structure of the synthesised compounds was confirmed through standard analytical techniques. Remarkably, both the elastomers displayed mesophase, despite the monomer and the cross-linker being non-mesogens. The mesophase was characterised by a combination of differential scanning calorimetry, polarising optical microscopy and X-ray diffraction experiments. The X-ray diffraction studies revealed an intercalated lamellar structure for the mesophase. Interestingly, the elastomer containing biphenyl-based cross-linker showed mesophase with an extended thermal range compared to the mesophase displayed by its counterpart containing phenyl-based cross-linker. The photoisomerisation behavior of the elastomers in solution and their photoswitchable properties in the solid state have been investigated. The monodomain sample of the elastomer showed a reversible, asymmetric bending and unbending behavior upon exposure to UV and visible light respectively, with a faster response time.

Efficient synthesis of macrocyclic paracyclophanes by ring-closing metathesis dimerization and trimerization reactions

(Matrix presented) Ring-closing metathesis reactions of para-disubstituted aromatic substrates produced macrocyclic [n.n]-, and [n.n.n]paracyclophanes efficiently through dimerization and trimerization reactions. Sufficiently long alkyl chains allowed direct monocyclizations to yield [n]paracyclophanes. A small library of paracyclophanes were generated by the combinatorial cross-metathesis approach.
