Isolable Dipyrromethene‐Based Heavier Group 14 and 15 Element Complexes

Résumé fourni par la source

Abstract Boron‐dipyrromethenes (BODIPYs) have attracted much attention owing to their unique properties and widespread applications; however, the incorporation of the heavier group 14 and 15 elements in the rigid dipyrromethene ligands remains limited. Herein, the dipyrromethene‐based heavier group 14 and 15 element complexes, tin‐dipyrromethene (SNDIPY, 1 ) and arsenic‐dipyrromethene (ASDIPY, 2 ), which are direct analogues of BODIPY, have been facilely synthesized and isolated in moderate yields. Both compounds have been investigated by NMR, UV‐vis absorption, photoluminescence spectroscopy, cyclic voltammogram, X‐ray crystallography, as well as theoretical studies. Both compounds exhibit green photoluminescence. Notably, SNDIPY 1 is air‐stable and compound 2 represents the first isolable and structurally characterized ASDIPY.
