Various novel types of supramolecular nanostructures formed by nonamphiphilic azobenzene derivatives, G1 or G2 have been successfully fabricated, where G2 is structurally similar with G1 but an extra phenoxy group is connected with the azobenzene motif. M
Photophysical properties of novel lanthanide (Tb3+, Dy3+, Eu3+) complexes with long chain para-carboxyphenol ester p-L-benzoate (L = dodecanoyloxy, myristoyloxy, palmitoyloxy and stearoyloxy)

In this paper, a series of 12 binary luminescent lanthanide coordination compounds with long chain p-carboxyphenol ester were assembled. Both elemental analysis and infrared spectroscopy allowed to determine the complexes formula: LnL3, where L

A variety of phenylbenzoates of the type (1) with both X and Y being the carbonyl containing chains (CH2)nCOR (n = 0 - 1), (CH2)nCO2R and (CH2)nOCOR (R = alkyl chain) in various combinations were synthesized and their mesomorphic properties studied to determine if an additive effect occurs when these chains are incorporated into the same molecule.No reliable additive effect could be found.Instead, clearing temperatures often seemed to be closer to the clearing temperature of the parent single carbonyl containing chain ester with the higher clearing temperature.An attempt was also made to improve the properties of the esters 1 with X or Y being I, F, CN or NO2 by using a carbonyl containing chain as the second substituent and assuming an additive effect.However, such an effect was also not observed in these esters.Smectic C phases were found in some of the esters with X = CN which is rare for compounds containing this substituent. - Keywords: liquid crystals, phenylbenzoates, synthesis, NMR, esters, ketones

A select number of 4-alkyl and alkoxyphenyl-4'-acyloxybenzoates and phenylthiobenzoates of the type where X = RCO2, Y = R' or OR', and Z = O or S have been prepared and their mesomorphic properties determined by hot-stage polarizing microscopy.T

The hydrolytic behavior of 21 para-substituted phenyl esters of n-alkanoic acids (n-X) with various chain lengths in 60:40 (Φ=0.60), 50:50 (Φ=0.50), and 40:60 v/v (Φ=0.40) Me2SO-H2O mixtures was studied.Four new sets of experimental results which include departure from Hammett correlation for N-hexadecanoates (16-X), substantial differences in activation parameters, and effects of amylose on the kinetic parameters and on the activation parameters are presented along lines of reasoning mentioned by previous authors.These data establish that the aggregation and self-coiling of the n-alkanoate chain actually exist under experimental conditions.
