A set of tetracyanoethylene (TCNE) substituted triphenylamine analogues (4–6) exhibiting strong intramolecular charge transfer (ICT) were designed and synthesized by the [2+2] cycloaddition–retroelectrocyclization reaction of 3 (tris-(4-phenylethynyl-phenyl)-amine) with TCNE. The reaction was found to be temperature dependent. The blue shift in the π → π∗ transition and intramolecular charge transfer
