TLDR
When silvery films of the semiconducting polymer, trans polyacetylene, (CH)x, are exposed to chlorine, bromine, or iodine vapour, uptake of halogen occurs, and the conductivity increases markedly (over seven orders of magnitude in the case of iodine) to give silvery or silvery-black films, some of which have a remarkably high conductivity at room temperature.Abstract:
When silvery films of the semiconducting polymer, trans‘polyacetylene’, (CH)x, are exposed to chlorine, bromine, or iodine vapour, uptake of halogen occurs, and the conductivity increases markedly (over seven orders of magnitude in the case of iodine) to give, depending on the extent of halogenation, silvery or silvery-black films, some of which have a remarkably high conductivity at room temperature.read more

Unimolecular Electronic Devices
TL;DR: The electrical contacts between metallic electrodes and organic molecular components are discussed, and representative organic wires composed of conducting groups and organic rectifiers composed of electron-donor and -acceptor groups are surveyed, and the Aviram-Ratner proposal for unimolecular rectification is proposed.

Synthesis of 2,′:5′,2″-terpyridine and 2,2′:5′,2″:5″,2‴-quaterpyridine and their photocatalysis of the reduction of water

TL;DR: In this article, a mechanism for the photocatalysis of hydrogen evolution is proposed in which the anion radicals supply electrons to protons on the metal colloids, resulting in the loss of photocatalytic activity.

Metal Complexes of π-Conjugated Polymers
TL;DR: In this article, π-conjugated chelating polymers such as poly(2,2′-bipyridine-5,5′-diyl) and salophen polymers have been prepared by organometallic polycondensations and obtained polymers form metal complexes with various metal species such as [Ru(bpy)2]2+ and CuCl2.
