Abstract

The ease of modification of boron dipyrromethene (BODIPY) enables the preparation of diverse structures with versatile optoelectronic properties. In this study, the synthesis and characterization of a new BODIPY derivative (4) bearing a methacrylate moiety at the meso position are reported. The BODIPY monomer (4) is polymerized with methyl methacrylate (MMA) as a comonomer and characterized via ¹H NMR and size exclusion chromatography (SEC). The resulting polymers, P[MMA-r-BODIPYMA] and PMMA are separately processed into nanofibers through electrospinning, and their morphologies are analyzed using a scanning electron microscope (SEM). Impedance analysis reveals that the impedance (Z) of the nanofibers decreases with increasing frequency up to ≈1 kHz, and remains constant beyond this point. The dielectric constant (ε′) and dielectric loss (ε′′) decrease, while AC conductivity (σac) increases with frequency. The impedance behavior of the nanofibers shows a linear relationship with frequency, indicating polarization under an alternating current electric field. Incorporating BODIPY into nanofibers reduces the dielectric constant due to alterations in dielectric polarization. These frequency-dependent impedance and dielectric properties suggest that the synthesized nanofibers have promising applications in nanotechnology-based electronic devices.
