structurally well-defined triarylethene-based extendedπ-systems have been prepared very rapidly. From a compound library constructed by the present method, it was possible to find a number of interesting fluorescent materials, as well as interesting fluorescent properties such as aggregation-induced enhanced emission. A useful method for the rapid synthesis and property evaluation has also been developed

Highly effective and selective Pd-catalyzed coupling reactions of 1,1-dibromo-1-alkenes with various arylboronic acids have been performed in aqueoussolution under mild conditions. The method is simple, economic, and practical for the synthesis of triarylethene-based compounds.
Titanium-multicarbene complexes, namely organotitanium species having a plurality of titanium-carbene complex substructures, were easily prepared by the reaction of aromatic nuclei possessing spatially separated thioacetal moieties with the titanocene(II) reagent Cp2Ti[P(OEt)3]2. Reaction of these multicarbene complexes with aromatic ketones gave various highly conjugated compounds in good yields.
