Bis(diaryl)-1,3-butadiynes bearing two amino moieties were easily synthesized by a sequential coupling reaction by using an electrochemical method. This sequential reaction consists of electrochemical oxidative homocoupling and Suzuki-Miyaura coupling. The fluorescence of the obtained bis(diaryl)-1,3-butadiynes is solvatochromic despite their symmetric linear structure and lack of a strong acceptor moiety.
