In this paper, we synthesized hypercross-linked conjugated chromophores with light absorption characteristics during cross-linking of aromatic monomers, such as naphthalene with dimethoxy methane, Phloroglucinol with terephthaldehyde and Phloroglucinol with dichloro-p-xylene from Friedal-Crafts reaction. DRS UV Vis spectroscopy confirms conjugated quinonoid matrix by their broad light absorption characteristics extending from 1000 to 200 nm. Absorbance maximum occurred close to 400 nm. So, the catalyst functions to cross-link the monomers by –CH2– bridges and subsequently dehydrogenate the bridges to form quinonoids. The FTIR spectroscopy showed their characteristic quinonoid vibrations between 1600 and 1700 cm-1. From the thermogravimetric analysis, thermal stability of the microporous polymers was found to be good. Their SEM images showed microspheres of 1 to 5μm size built with tiny particles. Their surfaces were not smooth. The maximum NOx sorption of 13% was obtained for the hypercross-linked polymer of Phloroglucinol with dichloro-p-xylene.
