The conformational behavior of the active C-terminal heptapeptide of neurotensin (NT), Pro-Arg-Arg-Pro-Tyr-Ile-LeuOH, or NT{7–13}, was investigated using empirical energy calculations. A sequential approach was used to display the specific contribu

The conformational behaviour of the basic hydrophilic Pro-Arg-Arg-Pro and Arg-Pro-Lys-Pro peptides, neurotensin (NT) and Substance P fragments, has been taken up by semi-empirical calculations. The presence of two Pro residues prevents these peptides

The metal cation (Ba++) binding ability of a family of designed nonconjugated bichromophoric [bis(para-phenylene)- or bis(para-diphenylene)]polyoxamacrocyclic coronands has been studied in acetonitrile in the ground state and in the singlet excited s

A bifurcated and an open chain (linear) can be introduced laterally into mesogens containing four rings in the main core. The racemic compounds give a narrow nematic range. The X-ray crystal structures of two isomeric compounds show that the bifurcat

A very favorable LUMO energy for cathodic electron injection is found in the crystalline state of the mesogenic red fluorescent perylene derivative 1. It is one of the rare cases where the columnar crystal structure of such a compound could be establ

The crystal structure of a 1,3-diacylaminobenzene, quite close to mesogenic diamide analogues, is described. The compound crystallizes in the P1 space group with two molecules per unit cell: a = 11.007 (2) A, b = 13.164(3) A, c = 8.806(3) A, α = 93.

The crystal structures of two chiral molecules giving a antiferroelectric mesophase have been solved. These structures and some other analogs (Hori et al) present the same characteristic features: they adopt a L-shape with their chiral alkyl chains p

A new chiral and semiperfluorinated series with ferro and anticlinic properties has been synthesized and characterized. The mesomorphic behaviour has been established on the grounds of both microscopic observations and DSC measurements. The non-chira
