Triphenylene derivatives possessing poly(ethylene oxide) (PEO) units exhibited discoticnematic (ND) phases at room temperature. Unique phase transition from a ND phase to a hexagonal columnar (Colh) phase was triggered by the addition of alkali metal salts. This phase transition was dependent on the type of the counterion of alkali metal salts added.

inspirations for designing new materials. Steroids form a diverse category of secondary metabolites, the derivatives of which constitute a prominent class of soft materials exhibiting various self-assembled structures. This report attempts to illustrate the importance of the oligo-ethyleneoxy side chain on the liquidcrystallinity of steroidal mesogens. The ethyleneoxy benzoates of sterols were found to

Disclosed is an optical compensatory sheet comprising a transparent support and an optically anisotropic layer provided thereon and having an optic axis inclined at 20 to 34 degrees from the normal of the sheet, wherein the optically anisotropic layer is formed from a discotic compound capable of forming a discotic nematic phase and an organic compound which has compatibility with the discotic compound and is capable of lowering a transition temperature of the discotic nematic phase by at least 10°C. Further, a liquid crystal display provided with the optical compensatory sheet is disclosed.

ACER3 inhibitors are lacking. Here we report on the synthesis and screening of two series of 1-deoxy(dihydro)ceramide analogs on the three enzymes. Activity was determined using fluorogenic substrates in recombinant human NC (rhNC) and both lysates and intact cells enriched in each enzyme. None of the molecules elicited a remarkable AC inhibitory activity in either experimental setup, while using rhNC,
