a Structural formulas of the adopted fourteen organic solvents in four categories, the red font is the dielectric constant (ε) of the corresponding solvents. b Schematic illustrates the form of AuH₂O NCs in organic solvents (DMSO and GL as representatives).c Steady-state emission spectra of AuH₂O NCs in H2O/DMSO, H2O/DMAc, and H2O/DMF, respectively (the volume ratio of aprotic solvent increased from top to bottom, i.e., AuDMSO-1 to AuDMSO-6, AuDMAc-1 to AuDMAc-6, and AuDMF-1 to AuDMF-6, λex = 365 nm). d Steady-state emission spectra of AuH₂O NCs in H2O/GL, H2O/PG, and H2O/EG, respectively (the volume ratio of proton solvent increased from top to bottom: i.e., AuGL-1 to AuGL-6; AuPG-1 to AuPG-6; and AuEG-1 to AuEG-6, λex = 365 nm). Insets are photographs taken under 365 nm UV light. R represents the ribosyl at the terminal of the 6-MPR ligand. Source data are provided as a Source Data file.
