Fluorescent Labeling Compound Linkers That Prevent Dye Quenching

The patent introduces a specific linker structure (Formula I) as an intermediary between phosphor moieties. This linker acts as a mediator that prevents direct interaction and self-association between dye molecules while maintaining their fluorescence properties. The linker structure with specific atomic composition and bonding pattern serves as a protective barrier that eliminates harmful intermolecular interactions.

The patent changes the structural parameters of the fluorescent compound by incorporating a specific linker structure (Formula I) with defined atomic composition and bonding patterns. This structural modification alters the physical and chemical properties of the phosphor moieties, preventing self-association while maintaining fluorescence intensity. The parameter change is reflected in the molecular structure and intermolecular interaction characteristics.

The linker structure (Formula I) serves as an intermediary that physically separates phosphor moieties and prevents energy transfer pathways that lead to quenching. By introducing this specific structural element, the patent blocks the harmful energy transfer between adjacent dye molecules while allowing each phosphor to maintain its individual fluorescence emission.

The patent segments the fluorescent compound into distinct units: phosphor moieties separated by linker structures (Formula I). This segmentation prevents the formation of continuous conjugated systems that would facilitate energy transfer and quenching. Each phosphor moiety becomes an independent fluorescent unit, eliminating collective quenching effects.
