摘要: Abstract Three perylenetetracarboxylic diimide (PDI) dimers linked with a conjugated chain of different lengths have been designed and prepared. The UV–Vis absorption fluorescence spectra these three revealed photophysical properties owing to the length linkage. intermolecular π–π interactions were found be enhanced significantly increase in linkage therefore induced aggregation behaviors molecules. structure molecular aggregates was investigated by X-ray diffraction (XRD), morphology examined atomic force microscopy (AFM). One-dimensional fibers observed for compounds 2 3, thin solid films compound 1.
