Abstract
We present here the results of our detailed optical, X-ray, high pressure and dielectric studies on 4-nonyloxyphenyl-4'-nitrobenzoyloxybenzoate (DB90NO 2), a triply reentrant compound which exhibits the following sequence of transitions at atmospheric pressure on cooling the isotropic phase : I—N—A d—Nre—Ad(re)—Nre—A 1—C—A2—C2. The existence of the A2 phase, not reported so far in this compound, is clearly shown from our studiesKeywords
