Abstract The development of near‐infrared (NIR) luminophores offers significant potential in the life sciences, yet constructing pure organic clusteroluminescence (CL) from nonconjugated polymers via through‐space interaction (TSI) remains a substantial challenge. Herein, it is revealed that sulfur (S) functions as bridge between isolated ester groups small molecule models, facilitating ( n , π*) transitions. Building on this, RCP1 ‐ RCP5 and P1 P4 are synthesized to produce NIR‐CL luminophores. introduction S enhances chain clustering polyesters modulates inter‐/intra‐chain TSI, while micro‐folding within chains promotes adjacent atoms, resulting marked redshift. Notably, displayed fluorescence peak at 800 nm, extending 883 which sets new record for CL. Additionally, full‐color fluorescent fibers fabricated explored application clusteroluminescent dyes. This work deepens understanding CL mechanisms provides critical insights developing high‐efficiency materials.
