Abstract

The preparation and self‐assembly of poly(2‐glucopyranosyl‐1,6‐naphthalene‐1,4‐phenylene), P16NP2Glu, an amphiphilic, blue‐light‐emitting copolymer, is reported. The copolymer is soluble in polar solvents such as methanol/THF mixtures and even in water. The emission spectrum of P16NP2Glu shows a maximum at ≈400 nm for solutions containing the above solvents. Owing to the highly polar nature of the glucopyranose rings of P16NP2Glu, the formation of aggregates is observed. Uniform‐size nanospheres capable of emitting blue light are prepared in the solid phase. The critical micelle concentration and micelle sizes are determined by light‐scattering measurements. It is found that the emission maximum and fluorescence quantum yields depend on the aggregate formation of the copolymer.
