Non‐alternant Benzodifluoranthene Tetraimides from 7,8,9,10‐Fluoranthene Diimides: Synthesis, Structure, and Optical‐Limiting Properties

A novel tetraimide‐functionalized non‐alternant π‐conjugated system, namely, benzodifluoranthene tetraimides (BDFTI), has been designed and synthesized through highly efficient UV‐photocyclization of a vinyl‐bridged fluoranthene diimide dimer (i. e., FDI−V). The synthesis of FDI−V starts from a stra...
