Five orthogonal smectic phases (Sm-A, Sm-Ab, Sm-APR, Sm-APAR, and Sm-APA) were observed in a 4-cyanoresorcinol bisbenzoate with twoterephthalate–based wings achiral bent-core(BC) compound. The phase behavior was investigated by polarising optical microscopy, second harmonic electro-optic response(EO2) and dielectric spectroscopy. The ﬁeld dependent biaxiality of polar and non-polar Sm-A phases was studied. It is obviously of enormous scientiﬁc signiﬁcance and practical interest to ﬁnd ﬁve different orthogonal smectic phases in a low molecular weight bent-core (BC) compound at relatively low temperatures.
