A new series of symmetrical 3,6-diphenyl-1,2,4,5-tetrazines with four alkoxy tails were synthesized along with new examples with two alkoxy tails. Mesogenic properties were studied by differential scanning calorimetry and polarizing optical microscopy. The influence of the number and length of alkoxy chains attached to the 3,6-diphenyl-1,2,4,5-tetrazine core is discussed. Compared with the two-tailed tetrazines, 6 the four-tailed liquid crystalline tetrazines, 5e-g possess lower smectic-C phase transitions, and clearing point temperatures.
