Organic π-conjugated laser materials have attracted much attention in the fields of optoelectronic devices and biosensing due to their tunable optical physical properties and low-cost processability. Among them, the trans-diphenylenyloxybenzene not only has a high fluorescence quantum yield, excellent stability and threshold laser emission performance, but also is a high-quality organic laser gain medium. This study, based on the molecular engineering strategy, synthesized three new DSB derivatives modified with phenyleneacetylene using dimethoxybenzene and bromobenzaldehyde as raw materials, explored the regulatory mechanism of molecular structure on the luminescence performance, and clarified the influence laws of conjugation length and substituents. The research results provide important theoretical and experimental support for the precise design of DSB functional materials and their applications in lasers, sensing, and optoelectronic devices.
