Derivatives of the cationic tropylium annulated imidazolylidene ITrop+ are obtained by hydride abstraction from related cycloheptatriene compounds. Spectroscopic, structural and theoretical data indicate that, as a cationic relative of benzimidazolylidenes, ITrop+ has highly reduced σ-donor and strong π-acceptor character.

Eighteen chromophores featuring 4,5-dicyanoimidazole as an acceptor moiety, a systematically enlarged π-conjugated spacer and methoxy and N,N-dimethylamino groups as donors were synthesised and characterised by X-ray analysis, electrochemistry, UV-Vis and fluorescence spectroscopy whilst NLO properties were calculated. Quantitative relationships between measured properties and structural features of the chromophores were also evaluated.
