Abstract
Correction for ‘Visible-light photooxidation in water by 1O2-generating supramolecular hydrogels’ by Sankarsan Biswas et al., Chem. Sci., 2020, 11, 4239–4245, DOI: 10.1039/C9SC06481H.
We regret that a related reference was omitted from the original article, which is given here as ref. 1. Draper et al. previously reported the synthesis of functionalized DPP with phenylalanine side chains. This structure is one of the low molecular weight gelators that we studied as a catalyst in our paper, although the aims of the two manuscripts are very different. Draper et al. used this molecule to show triggered hydrogelation by slowly decreasing pH. Finally, they studied electronic properties and alignment of these DPP-Phe fibers in the paper. Although we cited this work in our ESI, this work is relevant to our work and we would like to cite this paper in the main manuscript and acknowledge their work properly. Citations to ref. 1 should be included in the following sentences in the Introduction and Results and discussion sections:
On page 4239 in the sentence beginning “The assembly of the gels…” we would like to include a citation to ref. 1, in addition to ref. 35 in the original paper.
On page 4240 “We have assessed the catalytic activities of three such DPP-based supramolecular hydrogels that vary in their amino acid side chains, where they include either tyrosine (Y), phenylalanine (F)1 or leucine (L).”
On page 4240 “First, the DPP core was prepared by Dieckmann condensation of dimethyl succinate and thiophene-2-carbonitrile1 with 87% yield.”
On page 4240 “The core was then functionalized at the heterocyclic N with tert-butyl acetate via an SN2 substitution1 with 47% yield.”
The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
