Exciton migration! Spectroscopic analyses and extensive molecular dynamics studies revealed a well‐defined 41 helix in which the perylene molecules (see figure) form four “helter‐skelter‐like” overlapping pathways along which excitons and electrons can rapidly migrate.

A sensor to detect solid particles of a target salt can include a support substrate, an adsorption layer, a sensing layer oriented between the support substrate and the adsorption layer, and an electrode pair in contact with the sensing layer and separated by the sensing layer. The adsorption layer can include an ion exchange medium formed of a first porous structured material functionalized with basic or acidic functional groups. The basic or acidic functional groups can remove an acid or base component from the target salt to form a free base or free acid, respectively, of the target salt. The sensing layer can include a second porous structured material functionalized to detect the free base or acid of the target salt by a change in conductivity.
