Control of Liquid-Crystalline Properties by Base Pairing of Adenine and Thymine

Design of chiral dimesogens containing cholesteryl groups; formation of new molecular organizations and their application to molecular photonics

“…17 Cholesterol groups linked to a base like adenine or thymine through a methylene spacer have also been reported to exhibit cholesteric glassy liquid crystalline phase. 18 We have shown that from the hydrogen bonded liquid crystals formed between cholesterol containing hydrogen bond donors and cholesterol containing hydrogen bond acceptors glassy liquid crystalline films maintaining helical molecular order can be generated (6;Fig. 11) The relationship between liquid crystalline properties and alkyl chain length in these hydrogen bonded systems was also reported.…”

Playing with Liquid Crystals: A Short Review

“…HRXRD indicated that SmA phase in 61a was monolayer in nature where as for 62a it was partial bi layer. The liquid crystalline phase may be generated in this case due to attraction of opposite poles that may be due to polar and non-polar ends within molecule though there is instance of forming liquid crystalline phase in compound of these types due to H-bonding as in waston-Crick base pairing 47 .…”

Synthesis and phase transition studies of new dimer compounds connected to a 1,3-dimethylbarbituric acid core

“…In these compounds only the cholesteric phase has been observed. 18,19 However, there were several unsuccessful studies of the formation of lyotropic liquid crystals by DNA and nucleotides 20,21 and were done to prepare thermotropic liquid crystals of nucleobase derivatives. 22−24…”
