- The Synthesis of a novel tr?ger base polymer of 2,6(7)-Diamino-9,9,10,10-tetramethyl-9,10-dihydroanthracene
-
Condensation polymerisation technique has been employed to synthesise a Novel Tr?ger base polymer with thermal stability and microporosity. The synthesis process starts with alkylating anthracene, then nitrating and reducing this to produce the monomer. A Tr?ger base polymer is obtained by polymerising the monomer to afford a white polymer with good solubility into dichloromethane and chloroform, good thermal stability to ~ 377 °C and a good BET surface area of 368.6 m2/g with a total pore volume of 0.4166 ml/g.
