Convenient synthetic access to fluorescent rhodacyclopentadienes via ligand exchange reactions

Abstract: We have previously reported the formation of fluorescent 2,5-bis(arylethynyl)rhodacyclopentadienes from the reaction of [Rh(k 2-O,O-acac)(PMe 3) 2 ] (acac ¼ acetylacetonato) with a,u-bis(arylbutadiynyl)alkanes. However, a second isomer series, namely phosphorescent rhodium biphenyl complexes, was also obtained from the same reaction mixture, which made purification of the 2,5-bis(arylethynyl)rhodacyclopentadienes challenging and led to low isolated yields. Herein, we describe a synthetic protocol to access the… Show more

“…8 However, advances in this rapidly expanding field also include very recent examples of luminescent metal complexes of Ni(0) 9 , Pd(0), 10 and Rh(III). 11 The luminescent species including the above mentioned transition metal elements are not limited to mononuclear complexes, but include aggregated architectures with dominating metal-metal interactions as well as coordination polymers and clusters. On a broader overview, the area of metal-based luminescence indeed expands into quantum dots, nanoparticles and rare earths-containing species.…”
