Corrigendum: Ultralong Room‐Temperature Phosphorescence from Boric Acid

In this Research Article, wrong crystal data of boric acid (CCDC 1500066) were used for theoretical calculations. All theoretical calculations were now redone with the correct crystal data (ICSD 24711). Most of the theoretical data are similar (Figure 2 B, Figure 2 D and Figure 2 E). For the calculated R values (Figure 2 G), the data are different (but the trends similar), which can be ascribed to the geometry optimization procedure. Here, the newly optimized geometries are displayed (Figure 2 G) and calculated, yielding higher energy of T1 than in previous results. Although the exact R values are substantially different due to the change of ΔEST ( ), the trend is consistent with our description, namely, the R values of both Sn → Tn (1) and T1 → S0 (2) transitions decrease with the increasing number of packed BA molecules. Therefore, these corrections do not affect the conclusions of the published work. The authors sincerely apologize for this error.
