Synthesis and characterization of liquid crystalline organosiloxanes containing 4-methoxyphenyl 4-(2-alkenyloxy)benzoate

A series of new organosiloxane liquid crystalline materials based on the 4-methoxyphenyl-4-(ù-alkenyloxy)benzoate as mesogenic units have been synthesized and their mesomorphic and physical properties have been characterized. A series of new disiloxanes and trisiloxanes contain 4-methoxyphenyl 4-(ù-alkenyloxy)benzoate as mesogenic these were synthesized by addition of 4-methoxyphenyl 4-(ù-alkenyloxy)benzoate moiety to pentamethylhydrodisiloxane or heptamethylhydrotrisiloxane catalyzed by platinum divinyltetramethyldisiloxane complex. The thermal properties of this new series of thermotropic liquid-crystalline siloxanes were studied by differential scanning calorimetry and polarized optical microscope. Disiloxane series compounds were not showed any liquid crystal phase. Trisiloxanes series compounds exhibited nematic liquid crystal phase. The siloxane molecule helped to reduce the melting temperature. The thermal properties of the new siloxane series exhibited a pronounced odd-even effect with the length of alkyl segment.

Direct oxidative isoperfluoropropylation of terminal alkenes: Via hexafluoropropylene (HFP) and silver fluoride

A copper-mediated oxidative isoperfluoropropylation of unactivated terminal alkenes with commercially available hexafluoropropylene (HFP) has been developed. With operational simplicity of the procedure and broad substrate applicability, this strategy pro

Silicon-containing polyphilic bent-core molecules: The importance of nanosegregation for the development of chirality and polar order in liquid crystalline phases formed by Achiral molecules

Polyphilic molecules composed of a bent aromatic core, oligo(siloxane) units, and alkyl segments were synthesized, and the self-organization of these molecules was investigated. Most materials organize into polar smectic liquid crystalline phases. The swi

Induction of smectic layering in nematic liquid crystals using immiscible components. 1. Laterally attached side-chain liquid crystalline poly(norbornene)s and their low molar mass analogs with hydrocarbon/fluorocarbon substituents

{5-[[[2',5'-Bis[(4''-(n-(perfluoroalkyl)alkoxy)benzoyl)oxy]benzyl]oxy ]carbonyl]bicyclo[2.2.1]hept-2-ene]s were polymerized by ring-opening metathesis polymerization in THF at 40°C using Mo(CHCMe2Ph)(N-2,6(i)Pr2Ph)(O(t)Bu)2/sub

Use of intermolecular hydrogen bonding for the induction of liquid crystallinity in the side chain of polysiloxanes

A new type of liquid crystalline side chain polysiloxane has been built through self-assembly via intermolecular hydrogen bonding between H-bond donor and acceptor moieties. Poly(methylsiloxanes) and poly(methyl-co-dimethylsiloxanes) with side chains cont
