Making non-emissive 6cycloparaphenylene fluorescent by simple multiple methyl substitution

Key Points

• The addition of multiple methyl groups turns non-emissive [6]cyclingparaphenylene into a fluorescent compound, enhancing its light-emitting properties.
• Dodecamethyl[6]CPP was successfully synthesized using a gold-based macrocyclization method, demonstrating a significant alteration in properties.
• This method highlights a promising avenue for developing fluorescent compounds from previously non-emissive materials.
• Fluorophore characteristics were established, bolstering the understanding of structure-property relationships in cycloparaphenylenes.
