polyene character. On the other hand, resonance contributors can be rationalized for naphthalene and anthracene whereby one or two aromatic sextets evolve within the quinoidal structure thereby leading to a more localized electronicstructure. Monomer and polymer electronics were probed with UV−vis spectroscopy and cyclic voltammetry as well as through in situ profiling of the conductive states of the respective

the properties of polymers are fully investigated. The crystal structures and theoretical calculations show that through-bond and through-spaceconjugations are integrated into one single molecule, allowing for two transport channels in conjugated polymers, which is beneficial for improving the redox activity and stability. The multichannel transport by integrating through-bond and through-space conjugations

The present subject matter relates to display control in display devices. In an example implementation, a display control layer for a display device comprises a first set of channels filled with a first electrochromic material to control a view angle of a display from the display device, and a second set of channels filled with a second electrochromic material to control absorption of blue/ultraviolet (UV) light from the display device. Each adjacent pair of channels of the second set sandwiches a channel of the first set.
