In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Fabrication of microfluidic electrogenerated chemiluminescence cells incorporated with titanium dioxide nanoparticles to improve luminescent performances, published in 2020-10-31, which mentions a compound: 60804-74-2, Name is Tris(2,2′-bipyridine)ruthenium bis(hexafluorophosphate), Molecular C30H24F12N6P2Ru, Reference of Tris(2,2′-bipyridine)ruthenium bis(hexafluorophosphate).
We demonstrated microfluidic electrogenerated chemiluminescence cells incorporated with titanium dioxide nanoparticles (TiO2 NPs). SU-8-based microchannels were fabricated on a fluorine doped tin oxide cathodes-patterned glass substrate. TiO2 NPs were coated on the cathodes as an electron injection layer. The enclosed microchannels were achieved by a direct bonding of the SU-8 surface to an indium tin oxide anode-patterned polyethylene terephthalate film via vacuum UV treatment. A tris(2,2′-bipyridine)ruthenium(II) solution was used as an emitter. The proposed device exhibited a maximum luminance of 93.5 cd m-2 at 3.3 V, which is 1.45 times higher than that of device without TiO2 NPs.
Compounds in my other articles are similar to this one(Tris(2,2′-bipyridine)ruthenium bis(hexafluorophosphate))Reference of Tris(2,2′-bipyridine)ruthenium bis(hexafluorophosphate), you can compare them to see their pros and cons in some ways,such as convenient, effective and so on.
