Experimental and geometrical structure characterizations of new synthesized laterally fluorinated nematogenic system

Synthesis, Optical and DFT Characterizations of Laterally Fluorinated Phenyl Cinnamate Liquid Crystal Non-Symmetric System

“…The zero-point energy and other calculated quantum chemical parameters were predicted to increase when increasing the length of the molecule. Similarly, the polarity of the prepared compounds was predicted to increase with the length of the terminal chain, as indicated by the higher magnitude of the dipole moment with higher value of n. It was previously [24][25][26][27] reported that the planarity of the mesogenic portion of the LC compounds is enhanced by the mesomeric nature of the attached polar group. Hence, the conjugated π-cloud interactions, resulting from the terminal alkoxy group, offer a high thermal stability with suitable geometrical parameters, which is in agreement with the experimental findings in the present investigated series.…”

“…Moreover, they can generate photoactive LC materials because they can easily undergo trans/cis photo-induced isomerization. Thus, azobenzenes are also widely reported [13][14][15][16][17][18][19][20][21][22][23][24][25][26].…”

“…Generally, the mesomorphic ranges of nematic (N) phases are strongly enhanced when a lateral polar substituent is inserted to the mesogenic cores [24][25][26]. The extent of such impact is dependent on the volume, location, and polarity of the lateral group.…”

“…The lateral substituents decrement the intermolecular packing and effectively broaden the mesogenic core. This leads to lateral interaction depressions [25][26][27][28] and, consequently, the N thermal stability is reduced. It was documented by Gray et.al.…”

“…Our research lab has focused its interests on the computational studies of newly synthesized LC materials in order to investigate their mesomorphic behavior with the theoretical prediction relationship. Additionally, the design of new laterally substituted LC molecules resulted in a new geometrical property, and the N phases were observed [24][25][26][27]. In previous works [24][25][26][27], more investigations were directed towards analyzing the effect of introducing the lateral group in the central or terminal rings on their mesophase behaviors.…”
