1,8-Naphthalimide derivatives are highly fluorescent and photo stable and thus precursors for different applications e.g. in fluorescent synthetic polymers and textiles, fluorescent down shift materials as electro-optically sensitive materials, in laser technology, as liquid–crystal additives and as fluorescent markers in medicine and biology. In this work the defined naphthalimide-functionalized polymers are prepared using ring opening metathesis polymerization (ROMP). The influence of substituents at position 4 on the spectroscopic properties has been studied in norbornene monomers as well as in the corresponding polymers.
Due to the living polymerisation character and high functional group tolerance ROMP is suitable for the synthesis of defined (block) copolymers. Optical characterisations using absorption and emission spectroscopy show that monomers as well as the polymers have similar properties which mean that the covalent bonding to the polymer does not influence the characteristic properties of naphthalimide derivatives.
