A new class of discotics derived from tris(N-salicylideneaniline)s have been synthesized and their thermal and photophysical properties are investigated. These systems with outer 1,3,4-oxadiazole wings exist in an inseparable mixture of two keto-enamine tautomeric forms with C3h and Cs rotational symmetries, and self-assemble into fluid columnar phase over a wide thermal range as evidenced by several
