Terbium() bis-phthalocyaninato single-molecule magnet encapsulated in a single-walled carbon nanotube

In this study, terbium( iii ) bis-phthalocyaninato single-molecule magnets (TbPc 2 SMMs) were encapsulated in the internal nano space of single-walled carbon nanotubes (SWCNTs) for the first time. The magnetic and electronic properties of the TbPc 2 SMM-SWCNT hybrids were investigated in detail by using dc and ac magnetic susceptibility measurements, TEM, SEM, STM, STS, etc. By arranging the TbPc 2 SMMs in the one-dimensional internal nano spaces of SWCNTs, it is possible to investigate the essential SMM characteristics of TbPc 2 without considering ligand field (LF) effects. In addition, it appears that the electron correlation between TbPc 2 and the SWCNT can affect the electrotransport and/or electromagnetic properties. Furthermore, since the stable internal nano space of SWCNTs is used, it is thought that the density of SMMs in the SMM-SWCNT hybrid material can be controlled, and the hybrids should be usable as spin valves. Our strategy may pave the way for the construction of SMM-SWCNT hybrid materials. TbPc 2 SMMs were encapsulated in the internal nano space of SWCNTs for the first time. From the STM/STS, it was determined that there were electronic interactions between the TbPc 2 and SWCNTs in TbPc 2 @SWCNT.
