CF3-BODIPY形成强烈发光的聚集体，这与BODIPY染料典型的猝灭凝聚相光物理形成对比。通过检测这些聚集体的发光性质--狭窄的红移吸收和发射带、最小的斯托克斯位移和增加的荧光速率常数--以及染料的固态堆积，CF3-BODIPY成为第一个结构表征的真正的BODIPY J-聚集体。
A CF3-BODIPY forms strongly luminescent aggregates, which contrasts with the quenched condensed-phase photophysics that are typical for BODIPY dyes. Examination of the luminescent properties of these aggregates - narrow red-shifted absorption and emission bands, minimal Stokes shift and increased fluorescence rate constants - and of the solid-state packing of the dye establish the CF3-BODIPY as the first structurally characterized genuine BODIPY J-aggregate.
