In this work we report on gelation properties, self-assembly motifs, chirality effects and morphological characteristics of gels formed by chiral retro-dipeptidic gelators in the form of terminal diacids (1a–5a) and their dimethyl ester (1b–5b) a

Two realisations of solid-state environment, which differ in molecular packing, glassy and crystalline solid ethanol, are used as a model systems to study disorder in terms of nuclear spin bath frustration. It is probed by the hyperfine interaction o

Here we demonstrate that two extreme cases of molecular packing, i.e. the crystalline and glassy state of solid ethanol, which define the complete experimental span of attainable host matrix frustration, can be efficiently probed by measuring the ele

Thermotropic liquid crystal trans -4-heptylcyclohexanecarboxylic acid ( HCCA ) doped with 4-oxo-2,2,6,6,-tetramethyl-1-piperidinyloxy spin probe (Tempone) is investigated by electron spin resonance (ESR) spectroscopy in the presence of chiral bisoxal

The impact of geometrical frustration on electron spin decoherence pathways is studied by electron paramagnetic resonance spectroscopy (EPR) at X- and W-band frequencies. The glassy and crystalline state of solid ethanol served as a simple model of t

The complementarity principle, a basic concept of the crystal packing, is illustrated by the presented crystal structure optimising numerous noncovalent interactions: hydrogen bonding, C H⋯π, π⋯π interactions, and pronounced electrostatic inte

It is shown that continuous wave electron paramagnetic resonance (EPR) spectroscopy combined with pulsed mode EPR exhibits improvement in studying the structural and dynamic characteristics of gels. This approach applied on bis(leucine) oxalyl diamid

The phase transition phenomenon in solid ethanol doped with nitroxyl radicals was studied by continuous and pulsed electron paramagnetic resonance (EPR) spectroscopy. The appearance of the crystalline state from the ethanol glass was for the first ti

Four new chiral bis(amino alcohol)oxalamides (1-4: amino alcohol=leucinol, valinol, phenylglycinol, and phenylalaninol, respectively) have been prepared as low-molecular-weight organic gelators. Their gelation properties towards various organic solve
Electron paramagnetic resonance (EPR) signals induced by γ-radiation in different polymorphic forms of trehalose were studied with dosimetry applications in view. Dose response of trehalose in terms of the concentration of induced paramagnetic cente
