ABSTRACT A novel fluorescent benzoxazine (Bz) is synthesized from bio‐based amines, furfuryl amine, 2, 7‐dihydroxy naphthalene, and paraformaldehyde characterized using NMR IR spectroscopy. The Bz emits white light under UV irradiation, which sensitive to the presence of almost all transition metal ions exclusively, either by reducing intensity or completely shutting off emission. This nature may be used for sensing respective ions. DSC thermogram shows an exothermic peak at 255°C, indicating curing ring opening polymerization, confirmed FTIR spectra poly cured different temperatures. Poly has high thermal stability hydrophobicity with increase in temperature accounting its potential application aerospace electronic applications. Additionally, as polymer contains groups, low dielectric constant loss values, ideal materials uses like 5G technology high‐frequency circuits that demand fast signal transmission energy loss. study demonstrated synthesis monomer, behavior can life cycle analysis polymer.
