The final sentence of the experimental section of the above manuscript should read as follows: diethyl 9-(3,5-di-tert-butylphenyl)-9H-carbazoylphosphonate (23)³⁹, and 2,8-Dibromo-2',2″,7',7″-tetra-tert-butyl-dispiro(fluorene-9',6-indeno[1,2-b] fluorene-12,9″-fluorene) (28)^40-42 were prepared as previously reported.

Additional references should also be added as follows.

In the first paragraph of page 2: Compound 12 had diphenylaminostyryl at the C4 position of the tert-butylated spirofluorene core unit. In compounds 13 and 14, the spirofluorene core units were replaced by dispiroanthracene and dispiroindenofluorene.⁴³

In the first paragraph of page 8: The blue material 14 has a unique structure, double spiro-annulated structure connected indenofluorene core unit with extended conjugation system^40-42, whereas material 2 has a well-known spirobifluorene core.

The corresponding references should also be included in the above manuscript:
