Organic photoluminescent materials, such as fluorescent polymers and small fluorescent molecules, are widely used in optoelectronics, sensing, bioimaging, and related fields. However, their practical application is often limited by aggregation-induced fluorescence quenching in concentrated solutions or solid-state environments. To enable rational use of such materials, spectroscopic tools capable of detecting spectral manifestations of aggregation are essential. In this study, we proposed the use of synchronous fluorescence spectroscopy (SFS) to investigate aggregation-related spectral features in various polymer matrices containing phenyl-based chromophores and some aromatic compounds, including 9,10-diphenylanthracene, pyrene, anthracene, and naphthalene. SFS exhibited high sensitivity in identifying aggregate-related spectral features, including excimer-like emission and bathochromic shifts, both in solid matrices and liquid media. The results demonstrate that SFS is an effective diagnostic tool for probing aggregation behavior and optimizing the photophysical properties of polymeric luminescent materials.
