三甲基硅基、三甲基锗和三甲基锡基取代的芘的紫外吸收峰比未取代的茂的紫外峰移动了更长的波长。一、二、三、四(三甲基硅基)茂的最大吸收峰以10 nm为间隔连续向长波方向移动。荧光强度和寿命按Me_3SiAr&Gt；Me_3GeAr&Gt；Me_3SnAr的顺序递减。其中1，3，6，8-四(三甲基硅基)芘的荧光强度最大。
UV absorption maxima of trimethylsilyl-, trimethylgermyl-, and trimethylstannyl-substituted pyrenes shifted to longer wavelength than that of unsubstituted pyrene. Absorption maxima of mono-, bis-, tris-, and tetrakis(trimethylsilyl)pyrenes shifted to longer wavelength consecutively at intervals of 10 nm. Fluorescence intensities and lifetimes decreased in the order of Me3SiAr > Me3GeAr > Me3SnAr. Fluorescence intensity of 1,3,6,8-tetrakis(trimethylsilyl)pyrene was the largest among those of a series of pyrenes.
