Though investigated for decades, interest in push− pull chromophores (D− π− A), strong
electron donors (D) connected by π-conjugating spacers to strong electron acceptors (A) …

1, 2-Diethynylethenes (hex-3-ene-1, 5-diynes, DEEs) have found wide interest as potential
antitumor agents in medicinal chemistry1 and as redox active or chromophoric units in …

A wide variety of monomeric and oligomeric, donor‐substituted 1, 1, 4, 4‐
tetracyanobutadienes (TCBDs) have been synthesized by [2+ 2] cycloaddition between …

Tetracyanoethylene (TCNE) undergoes numerous reactions and is reported to exist in many
structural motifs. Identification of these forms and motifs can be challenging. Nonetheless …

Rivaling the best one: Thermal [2+ 2] cycloadditions of TCNE, TCNQ, and F4‐TCNQ to N, N‐
dimethylanilino‐substituted cyanoalkynes afforded a new class of organic super‐acceptors …

The review summarises data on transition metal complexes with the so-called non-innocent
ligands. The specific feature of these complexes is that the oxidation state of the central …

An extensive series of silyl‐protected cyanoethynylethenes (CEEs) and N, N‐
dimethylanilino donor‐substituted CEEs have been synthesized. More extended …

Our group started a research program in acetylene chemistry in 1987; since then, an intense
research effort led to a fascinating journey into acetylenic scaffolding, aimed at exploring …

Stable, highly colored push‐pull chromophores with NMe2 donor and C= C (CN) 2 acceptor
moieties, featuring intense intramolecular charge‐transfer (CT) bands in the UV/Vis spectra …

Donor-substituted 1, 1, 2, 4, 4-pentacyanobuta-1, 3-dienes and a cyclohexa-2, 5-diene-1, 4-
diylidene-expanded derivative were prepared by a [2+ 2] cycloaddition of tetracyanoethene …
