| Metal-organic frameworks (MOFs) have been a recent topic of interest because they can be utilized as materials for molecular storage, sensors, and catalysis. Various studies have reported applications of MOFs in carbon dioxide and hydrogen storage. The functionality of MOFs will be greatly enhanced by the ability to fluoresce. This enhancement may be accomplished by the use of fluorescent ‘metalloligands.' Bis-(5-mesityldipyrrinato)zinc complex has been shown to be fluorescent (JACS 2004, 126, 2664-2665.) This study focuses on forming MOFs using three-fold symmetrical dipyrrinato complexes. Group 13 metals with a 3+ oxidation state have closed-shell electron configurations that also results in the formation of luminescent dipyrrin complexes. Tris-(5-mesityldipyrrinato)gallium and tris-(5-mesityldipyrrinato)indium were synthesized and shown to fluoresce at 365 nm excitation with a green emission centered at 528 nm. Further studies will be focused on the synthesis of MOFs using analogs of dipyrrin-based metalloligands. |
