| Abstract: | New water-soluble heteroligand complexes of 2-methyl-4-oxo-4H-pyran-3-olatoneodymium(III) with aliphatic amino acids (glycine, N-methylglycine, and alanine) have been prepared. Within the biological “transparency window” (700–900 nm) of their electronic absorption spectra, narrow bands of Nd3+ are found: 4F7/2 ← 4I9/2; 4F5/2 ← 4I9/2; 4F3/2 ← 4I9/2 (750, 810, and 880 nm). Such complexes can be used as markers for biological tissues visualization. |
