An account（in Japanese: 総合論文）on the development of aromatic-fused diketophosphanyl functionalized π-conjugated molecules (doi: 10.5059/yukigoseikyokaishi.78.792) has come out on Journal of Synthetic Organic Chemistry, Japan (有機合成化学協会誌). The aromatic fused-diketophosphanyl compounds is regarded as a surrogate of aromatic-fused imide compoudns, which are often used as a good electron-transporting materials. Enjoy the exotic structure and functions of the unique molecules!
