In this work, three synthetic methodologies of 2,2′,4-trifluoro-4”-alkyl-[1,1′:4′,1”]terphenyls were presented. The most convenient synthetic method was used for homologous series of 2,2′,4-trifluoro-4”-alkyl-[1,1′:4′,1”]terphenyls (alkyl chain from Me to hexyl). The results showed that fluorination in the inner-core position (at 2 and 2′ position of terphenyl core) promoted only a nematic phase. The results was discussed with other chloro- and fluoro- substituted 4”-alkyl-[1,1′:4′,1”]terphenyls and one perdeuterated terphenyl analog. The synthesis and purity of synthesized compounds were monitored by gas chromatog. GC-MS, GC-FID and by thin layer chromatog. (TLC). The phase situation and the phase transition temperatures were determined by polarized optical microscopy (POM). The temperatures and enthalpies of the phase transitions were measured by using differential scanning calorimetry (DSC).
