In recent years, non-conjugated organic luminophores are receiving considerable interest from the scientific community, offering new conceptual basis for the development of alternative photoluminescence-based technologies. In this work, the polymerization of 3,4dihydropyran was exploited for the preparation of non-conjugated photoluminescent polymer nanoparticles. Remarkably, excitation-dependent multicolor emission ranging from blue to yellow 2 was observed both in solid and in solution. In contrast with similar materials, this behavior was not attributed to aggregation-induced emission, but rather to the presence of independent, noninteracting chromophores located on the polymer structure. Structural and optical characterization along with further chemical modifications suggest that the emission is related to the presence of acetal groups formed by ring-opening polymerization. In addition, it was shown that the removal of unsaturated structures could enhance the photoluminescence quantum yield of the polymer (QY) up to 0.20 (λex = 355 nm). This work provides a new type of non-conjugated organic luminophore with both high QY and multicolor emission.Read less <
