Original Abstract

The efficiency of SSF depends on the combination of intermolecular and intramolecular processes that can cause either quenching or enhancement of photoluminescence quantum yield (PLQY). Therefore, to under- stand and effectively utilize the relationship between the optical properties of materials and their modified structure is very much desired. In this work, the optical properties of a series of new π-conjugated DPA DPS EWG were investigated. By varying the strength of the EWG, the LUMO energy could be tuned, resulting in a change of the SSF maxima in the interval from 380 nm to 630 nm, covering a range of 250 nm. These results demonstrate the potential of such an approach for the development of multicomponent white-light-emitting materials.
