An additional correction was to delete the red cross for the excitation energy at the CAM-B3LYP level in Figure 7.Furthermore, in the discussion of electronic character for the S 3 state in Table S3 (Supporting Information), "HOMO-1!LUMO(21%) 2!2" should be replaced by "HOMO-1!LUMO(21%) 2!3".We apologize for any inconvenience caused by above misprints.
