Highly refractive and transparent polyphosphonates with varying aromatic backbones have been synthesized by polycondensation of phosphonic dichlorides and diols, significantly expanding the reported scope of these intrinsic high refractive index polymers. The polyphosphonates display excellent thermal properties, with thermal stability up to 450°C and tuneable glass transition temperatures ranging from 41 to 214°C by terminating the polymer with different alcs. The polymers synthesized also possess excellent optical properties, with low UV cut off points and high refractive indexes up to 1.66, the highest reported for this type of polymer. We also report Abbe numbers for this class of polymers for the first time; all are high (>22), making these polymers excellent potential candidates for a range of optical applications. This study involved multiple reactions and reactants, such as 4-Chlororesorcinol (cas: 95-88-5Electric Literature of C6H5ClO2).
4-Chlororesorcinol (cas: 95-88-5) belongs to organic chlorides. Organic chlorides are compounds containing a carbon-chlorine bond, which are widely used in the oil field as a wax dissolver. Alkyl chlorides readily react with amines to give substituted amines. Alkyl chlorides are substituted by softer halides such as the iodide in the Finkelstein reaction.Electric Literature of C6H5ClO2
