A novel diphenylacetylene derivative having an imide group was synthesized by introducing an octadecyl chain into diphenylacetylene compound containing phthalic anhydride, and a polymer was obtained using a group V transition metal catalyst and its fluorescence emission and physical properties were evaluated. This polymer was characterized by FT-IR and NMR spectroscopy analysis, and thermodynamic/structural/optical properties were evaluated through XRD, DSC, UV absorption and fluorescence emission spectroscopy analyses. Our research group has been conducting research on various polydiphenylacetylene derivatives. The newly synthesized polymer emits blue fluorescence, which exhibits a very specific fluorescence emission color compared to other polymer derivatives emitting yellow-green fluorescence. In this study, new applications are being explored using this novel polymer derivative.
