Herein, we report the fabrication of organic nanofibrils, using electrospun 3-oxime-4-hydroxy-1,8-naphthalic- n -butylimide ( R1 )-doped polycaprolactone (PCL), for application as a gaseous phosgene-specific sensing device. The phosgene-mediated adsorption of the nanofibers gives rise to an observab...
