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.

本文合成了一系列噻吩基甲烷衍生物。这些衍生物比相应的线性类似物具有更长的吸收和荧光波长。值得注意的是，这些衍生物不仅具有高度对称的分子结构，而且具有高结晶倾向，而且具有基于许多稳定构象的稳定无定形状态。
