Synthesis and characterization of glycidyl ethers modified by mesogenic units

The effect of mesogenic length on the curing behavior and properties of liquid crystalline epoxy resins

“…Ober et al synthesized symmetric twin LCE resins [9] and Jahromi et al [10][11][12][13] and Broer et al [14] reported the curing reaction of aromatic ester based LCE resins. In addition, biphenol epoxy resin [8,[15][16][17], azo epoxy resin [16], chalcone epoxy resin [18], azine epoxy resin [19], azomethine [20] and binaphthyl epoxy resin [21] were studied by many research groups. These studies mainly reported the curing behavior, anisotropic orientation and morphology of cured liquid crystalline thermosets.…”

Synthesis of New Epoxy Liquid-Crystalline Monomers with Azo Groups in the Central Mesogenic Core. Crosslinking with Amines

“…To our knowledge, there is only one reference in the literature where the mesogen is an azobiphenolic ether which has a nematic mesophase with a narrow range of stability. [10] The proposed structures of the resins contain spacers of different lengths between the mesogenic core and the glycidylic group. These different lengths lead to changes in the melting and clearing points and influence the mobility in the reorientation processes.…”

Effect of backbone moiety in diglycidylether-terminated liquid crystalline epoxy on thermal conductivity of epoxy/alumina composite

“…It is known that LCE species bearing various mesogenic units in structure, such as azo [2,3], stilbene [4][5][6][7][8][9][10][11][12], biphenyl [13][14][15][16], binaphthyl [17,18], azine [19], ester [20][21][22][23][24][25], and azomethine [26][27][28][29][30], are widely used as thermosetting resins as well as liquid crystalline polymers. Many research groups have reported the synthesis, curing behavior, and mechanical properties of epoxy containing liquid crystalline structures, but only a few articles have been published on the thermal conductive property of LCE based on above mentioned mesogens.…”
