An increasing number of studies take advantage of ion mobility spectrometry (IMS) coupled to mass spectrometry (IMS‐MS) to investigate the spatial structure of gaseous ions. Synthetic polymers occupy a unique place in the field of IMS‐MS. Indeed, due to their intrinsic dispersity, they offer a broad range of homologous ions with different lengths. To help rationalize experimental data, various theoretical...
Conjugated polymers have demonstrated to express chirality, for instance, by strong circular dichroism (CD). However, the shape and intensity of the spectra can be quite different and are very difficult to predict. Molecular irregularity, star‐shapes, and linking polymers have demonstrated to affect the CD, often in a positive way. In this research, we design two different chiral arms, in which the...
Saponins are amphiphilic molecules of pharmaceutical interest and most of their biological activities (i.e., cytotoxic, hemolytic, fungicide, etc.) are associated to their membranolytic properties. These molecules are secondary metabolites present in numerous plants and in some marine animals, such as sea cucumbers and starfishes. Structurally, all saponins correspond to the combination of a hydrophilic...
