The authors regret that the incorrect reference was cited as ref. 13. The correct reference is shown below.

In the cited paper, the preparation procedure for compound 1 is not described. The preparative method for 1 is as follows. The authors apologize for the inconvenience this may have caused.

Preparation of 1: To a 300 mL flask were added Ar,O-BODIPY S1 ¹⁰ (588.2 mg, 1.076 mmol), methanol (100 mL), and conc. HCl aq. (5 mL). The mixture was stirred at room temperature for 19 h. To the reaction mixure were added sat. NaHCO₃ aq. (100 mL) and EtOAc (100 mL). The organic layer was separated, and the aqueous layer was extracted with EtOAc (50 mL × 2). The combined organic layer was dried over Na₂SO₄, filtered, and concentrated in vacuo. The residue was purified by column chromatography (silica gel, EtOAc/hexane = 1/8) to give 1 as a red solid (476.0 mg, 1.034 mmol, 96%). ¹H NMR (400 MHz, CDCl₃): δ 12.92 (br), 11.96 (br), 7.75 (dd, J = 7.8, 1.4 Hz, 1H), 7.69 (dd, J = 7.8, 1.5 Hz, 1H), 7.32–7.26 (3H), 7.08–6.99 (4H), 6.96 (s, 2H), 6.93 (d, J = 7.1 Hz, 1H), 6.74 (d, J = 4.6 Hz, 2H), 6.30 (br), 3.96 (s, 3H), 2.38 (s, 3H), 2.14 (s, 6H).
