Nowadays liquid crystal (LC) substances possess a wide range of uses. However, it is rather rare that a single organic
technique for determining changes in chemical interactions and molecular geometry in LC phases [37][38][39][40], we investigated the 73 mol % BB mixture using temperature-dependentFTIR measurements. IR spectra were recorded using a KBr pastille method. Since in a binary mixture the cyano group of CBI may
compounds [51]. This data combined with the temperature-dependentFTIR measurements suggest that a specific interaction between the different mesogenic groups is not particularly strong. According to the phase diagram, the induced smectic phase is most stable in the mixture containing roughly 70 mol % of BB
