Aspects of the Chemistry of Species with Carbon–Polonium Bonds

Abstract

The chemistry of compounds with carbon‐polonium bonds remains, not surprisingly, rather unstudied because of the high level of radioactivity, and hence scarcity, danger and expense, associated with polonium itself. Attempts to enlighten this understanding have rarely investigated the same species experimentally and theoretically; the former are emphasized in this chapter. Approaches to the syntheses of dialkyl polonides, aryl polonium derivatives and other types of compounds with carbon‐polonium bonds are discussed.

Influence of the Synthesis Parameters on the Properties of NaYF4:Yb3+,Tm3+ Nanoparticles

“…19 The studies on the potential leakage of the RE 3+ or the Ffrom the fluoride UCNPs in the water and the potential (cyto)toxicity in a biological environment were limited and tended not to reveal any significant cytotoxicity. [20][21][22][23] Nevertheless, greater concern should be paid to the long-term toxicity effects of RE 3+ and F -, which might be released from fluoride UCNPs. For example, Gd ions released from Gdbased MRI contrast agents were reported to induce nephrogenic systemic fibrosis.…”
