In this paper, we report two simple and effective bromination methods to brominate the cyclo olefin copolymer (COC). A suitable metallic catalyst can accomplish functionalization and chromophorization of the brominated COC. A 2nd NLO dye, Disperse Orange 3(DO3) containing the -NH2 functional group, has been grafted onto either the norbornene unit or the PE segment of the COC backbone successfully, by the palladium catalyst, Pd2(dba)2(Bis[dibenzylideneacetone] dipalladium). The observed low dye grafting content can be attributed to the higher hindrance of the norbornene ring. Based on UV results, the NLO-COC, having dye grafted onto the norbornene unit shows more red shift than that grafted onto the PE unit, probably due to greater shielding on the chromorphor.
