Research Abstract

A series of the derivatives of tetrakis(2-thienyl)methane extended with further thiophene rings have been synthesized. These derivatives exhibited the longer absorption and fluorescence wavelengths than those of the corresponding linear analogues. It should be noted that these derivatives not only showed the high tendency to crystallize reflecting the highly symmetric molecular structure but also the stable amorphous state based on the many stable conformers.
