Two families of positional isomers of dispirofluorene-indenofluorene substituted by phenyl groups at the 2,7-positions of the fluorene moieties present drastically different optical properties. The emission wavelengths may be gradually and conveniently modulated for one of the two isomers by the phenyl group's substituent whose bulkiness controls the extent of the excimeric interaction evidenced in this paper.
芴部分的2,7位被苯基取代的双螺芴-茚并芴的两个位置异构体家族呈现出截然不同的光学性质。对于这两种异构体中的一种，芴部分的发射波长可通过苯基取代基进行逐步且方便的调节，该取代基的体积控制了本文所证明的准分子相互作用的程度。
