Synthesis of Novel Scolopendra-Type Polydodecyloxybenzoyl[1,5]-diazocine as New Material for Optical Sensor

A new scolopendra-type polymer of polydodecyloxybenzoyl[1,5]-diazocine (PDBD) was designed and prepared using 2,5-bis(4-(dodecyloxy)-benzoyl)terephthaloyl azide with trifluoroacetic acid (TFA) via one-pot reaction in good yields. The structure of polymer was characterized using 1H-NMR, 13C-NMR and MALDI-TOF spectra. The polymer PDBD exhibits good thermal stability as measured by TGA and DSC, and can be dissolved well in common organic solvents such as chloroform and tetrahydrofuran. In addition, UV-Vis spectral studies indicate that the polymer PDBD shows unique optical property changes (protonation/deprotonation) in the different trifluoroacetic acid environments. The new polymer is expected to be utilized as an optical functional material for fabricating optical sensors in environmental and biological fields.
