摘要

Polymers and molecular materials bearing heterocyclic moieties have attracted great attention in diverse areas like optoelectronics, energy storage and corrosion inhibitors etc., where the heterocyclic moiety plays a crucial role in tuning the property to achieve desired applications. In this work, we synthesised new monomer, 2-Allyl-4,5,6,7-tetrabromoisoindoline-1,3-dione (2-ATBII-1,3-Dione) and was polymerized successfully in a two phase system using di-site phase transfer catalyst (1,4-bis (triethylmethylammonium benzene dibromide) (TEMABDB) and potassium peroxydisulfate (PDS) as a water-soluble initiator at 80 ± 2 °C under sonication (45 kHz; 550 W) and silent conditions. Polymerization rate was raised under sonication than conventional methods. Impact of various kinetic parameters was examined in detail for both conditions. The synthesised monomer, 2-ATBII-1,3-dione and poly(2-ATBII-1,3-dione) were characterised by UV–vis, FT-IR, 1H NMR, XRD and SEM analyses and their features were discussed.
