Abstract

Correction for ‘Harnessing an emissive guanine surrogate to design small-molecule fluorescent chemosensors of O⁶-methylguanine-DNA-methyltransferase (MGMT)’ by Alexandra Fillion et al., Org. Biomol. Chem., 2022, 20, 1888–1892, https://doi.org/10.1039/D2OB00208F.

The authors regret that there were some errors in Table 1. The correct table is shown below.

Table 1 Photophysical data for O⁶-substituted ^thG_N derivatives in water^a

Compound	λ abs,max/nm	ε/cm^−1 M^−1	λ em,max ^b/nm	Φ
a c = 50 μM for absorbance, 5 μM for fluorescence measurements. b λ ex = 325 nm. c Fluorescence quantum yield, reference: quinine sulphate in 0.5 M H2SO4 (Φ = 0.546). d This value is higher than the one reported in the literature (0.46)^28 presumably due to the use of another quantum yield standard.
^thGN	315	3100	436	0.59^d
^thGEt	337	3140	448	0.47
^thGB	339	3240	449	0.28
