MHz for H and 101 MHz for C, respectively, in CDCl3, Methanol-d3, and DMSO-d6 solutions provided by Eurisotop, using TMS as an internal reference. Chemical shifts are reported in ppm on the δ scale. Multiplicities are denoted as s (singlet), d (doublet), dd (doublet of doublet), t (triplet), q (quartet), m (multiplet), and coupling constants (J) are reported in Hz. High-resolution mass spectra (HRMS) were acquired in electrospray ionization (ESI) mode using an LC-MSD TOF mass analyzer. UV-Visible spectra were obtained using the DR3900 spectrophotometer and processed with Origin Pro.
