Competitive supramolecular assembly tunes anthracene emission over 165 nm via controlled π-overlap

Key Points

• The study aims to explore how competition between different bonding types influences anthracene emission properties.
• Investigation of hydrogen-bonding and B←N coordination in assembly of specific compounds.
• Identification of five distinct crystalline phases based on assembly variations.
• Quantitative measurement of anthracene π-overlap area.
• Variations in anthracene π-overlap range from 0 to 64.5%.
• Distinct crystalline phases exhibit different emission properties, tuned by assembly competition.
• Solid-state anthracene emission is significantly modulated over a range of 165 nm.
