Steric effects in the reaction of aryl radicals on surfaces.
TL;DR: These experiments, together with density functional computations of bonding energies of substituted phenyl groups on a copper surface, are discussed in terms of the reactivity of aryl radicals in the electrografting reaction and in the growth of the polyaryl layer.

TL;DR: In this paper, a grafted nanometer thick polyphenylene film is obtained from visible irradiation of a gold surface dipped into a solution of diversely substituted aryldiazonium salts in the presence of a photosensitizer (Ru(bipy)32+ or eosinY).

TL;DR: In this paper, a selective synthesis of unsymmetrically substituted electron donor/electron acceptor biaryls is described which is based on an electrochemically or photochemically induced SRN1 reaction; the optical hyperpolarizability coefficients β are determined in solution for the various reaction products and found to be of the same order of magnitude as that of 4-nitro-aniline.

Electrosynthesis of unsymmetrical biaryls using a SRN1 type reaction
TL;DR: In this article, a new synthetic route to unsymmetrical biaryls was described involving an electrochemically induced chain reaction of the S RN 1 type, which was described as an alternative to the traditional S RN 2 type.
