一种嵌入聚合物的树枝状、基于BODIPY的全色吸收体具有内置的能量梯度，将入射的太阳辐射集中在终端生色团上，导致指向聚合物波导侧面的单色发射(见图)。这种特殊的设计使外围天线单元的自吸收损耗降至最低，S系数为10000，令人印象深刻。
A polymer-embedded dendritic, bodipy-based panchromatic absorber with a built-in energy gradient concentrates incident solar radiation at a terminal chromophore, resulting in a monochromatized emission directed to the sides of the polymer waveguide (see picture). This particular design minimizes self-absorption losses from the peripheral antenna units with an impressive S factor of 10 000.
