correct 1H NMR | soluble | SNE with photo-CIDNP NMR | total |
---|---|---|---|
277 | 262 | 212 | 287 |
97% | 91% | 74% | 100% |
First 287 molecules are selected to have a most central aromatic ring yielding photo-CIDNP SNE. Second, a 1D 1H NMR experiment of each compound (200 μM) is recorded in the presence of 100 μM DSS as a reference signal, and the signal intensity is compared to the DSS to ensure that the compounds are present at a concentration of at least 100 μM. Finally, the photo-CIDNP signal is recorded, and observation of SNE > 5 is the final criterion for inclusion.
