Abstract Peptide-like foldamers controlled by normal amide backbone hydrogen bonding have been extensively studied, and their folding patterns largely rely on configurational and conformational constraints induced by the steric properties of backbone

Abstract Planar chiral [2.2]paracyclophanes consist of two functionalized benzene rings connected by two ethylene bridges. These organic compounds have a wide range of applications in asymmetric synthesis, as both ligands and catalysts, and in materi

The scope of Rh-catalyzed C–C bond cleavage/annulation of biphenylene with various aromatic nitriles was studied. The subsequent Rh- and Ir-catalyzed C–H bond activation/annulation sequence of the formed 9-arylphenanthridines with alkynes gave ri

Complexes of Cu(ii) with studied ligands show very short NMR longitudinal relaxation times T1 of 19F nuclei and good T2*/T1 ratio. Thus, Cu(ii) can be considered as a suitable metal ion for the design of efficient 19F MRI/NMR relaxation agents.

Optical and semiconducting properties of vacuum-deposited thin films of four hydrogen-bonded pigments were studied. Well-known 1,4-diketo-3,6-diphenyl-pyrrolo-[3,4-c]-pyrrole (Ph-DPP) and 1,4-diketo-3,6-(thiophen-2-yl)-pyrrolo-[3,4-c]-pyrrole (Th-DPP
