Case Study

1,4-Bis-[4-(3-Acryloyloxypropyloxy)Benzoyloxy]-2-Methylbenzene Used to Prepare Polymer Network Liquid Crystals

Wang, Kemeng, et al. Liquid Crystals, 2021, 48(7), 945-954.

The polymer network liquid crystal system received combination of 1,4-bis-[4-(3-acryloyloxypropyloxy)benzoyloxy]-2-methylbenzene (RM257) and 1-ethynyl-4-(trifluoromethyl)benzene (ETB) to reduce the threshold and saturation voltage and hysteresis. The operating voltage in the polymer network liquid crystal decreased by 51.5% and hysteresis reached 0.38 V when RM257 and ETB were present at 5% and 1% weight contents respectively.
Sample preparation
The liquid crystal polymer monomer RM257 and ETB are blended in varying proportions. The resulting mixtures are then heated and stirred with a magnetic stirrer in a dark environment to achieve uniformity. Subsequently, these mixtures are injected into an 8 μm thick LC cell, featuring polyimide layers on the inner surfaces without rubbing, using capillary action, and cured under UV light for 15 minutes. Both the filling and curing processes are conducted at a temperature of 65°C.

1,4-Bis-[4-(3-Acryloyloxypropyloxy)Benzoyloxy]-2-Methylbenzene Monomer for the Preparation of Liquid Crystal Elastomers

Xia, Yu, et al. Angewandte Chemie, 2018, 130(20), 5767-5770.

This work utilized oxygen-mediated click reactions between commercially available dithiols and diacrylates to produce main-chain liquid crystal elastomers (LCEs) that are arranged through microchannels. Efficient photocross-linking chemistry based on a two-step oxygen-mediated thiol-acrylate click reaction allows for almost immediate gelation of the main-chain LCE network upon UV exposure.
The experiment utilized two commercial diacrylate liquid crystalline monomers (LCMs) namely 1,4-bis-[4-(3-acryloyloxypropoxy)benzoyloxy]-2-methylbenzene (RM257 with m = 3) and 1,4-bis-[4-(6-acryloyloxyhexyloxy)benzoyloxy]-2-methylbenzene (RM82 with m = 6) along with 1,3-propanedithiol (n = 1) and 1,5-pentanedithiol. Research showed that longer chain dithiols with chain lengths greater than three units can also be employed in the synthesis of liquid crystalline elastomers.
The distinct chemical and physical properties between mesogenic diacrylates and nonmesogenic dithiols result in phase separation during mixing where nematic domain tactoids separate from thiol-rich isotropic liquids. To circumvent this problem, prepolymerized diacrylates with dithiols at a molar ratio of 1: The strong base catalyst 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) was used to produce a series of short-chain mesogenic dithiolterminated oligomers. The product RM257-1,3DT results from the combination of RM257 with 1,3-propanedithiol.
