Correction: Synthesis and structural characterization of metal complexes with macrocyclic tetracarbene ligands

Abstract

Correction for ‘Synthesis and structural characterization of metal complexes with macrocyclic tetracarbene ligands’ by Fan Fei et al., New J. Chem., 2017, 41, 13442–13453.

The authors regret that the excitation wavelengths λ_ex for complexes 1, 4 and 5 are incorrect in the published article. They should be 340 nm for 1, 345 nm for 4 and 340 nm for 5. Thus, the sentences on p. 13447, left column, line 12 should read:

The emission spectra in acetonitrile solution (1.0 μM) show a band at 402 nm (λ_ex = 340 nm) for 1 and two bands at 405 nm and 532 nm for 4 (λ_ex = 345 nm) (Fig. 5), corresponding to the blue-violet and yellow-green emissions, respectively. Compared to 1 and 4, the emission spectrum of 5 shows two weak bands at 389 nm and 520 nm (λ_ex = 340 nm) (Fig. 5). The emission quantum yield (Φ) of 4 was determined to be 0.28 (λ_ex = 345 nm) relative to quinine sulfate,^24,25 while that of 5 was very low, below 0.05 (λ_ex = 340 nm).

In addition, the caption of Fig. 5 should read:

Fig. 5 (upper) Absorption spectra of (H₄L¹)(PF₆)₄ (black), 1 (red), 4 (green) and 5 (blue). (bottom) Emission spectra of 1 (red, λ_ex = 340 nm), 4 (green, λ_ex = 345 nm) and 5 (blue, λ_ex = 340 nm). All the samples were 1 μM in acetonitrile.

In the ESI, page 12, the excitation wavelength used to measure the emission quantum yield of 4 should be 345 nm. The ESI was corrected on 25th April 2018.

The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
