Formation of ultra-long nanoribbons by self-assembly of carbon dots and anionic oligomers for multi-colored fluorescence and electrical conduction

We report a facile and scalable synthesis of ultra-long (>100 μm) nanoribbons based on self-assembly of positively charged carbon dots (C-dots) and anionic oligomers of styrene and 4-styrenesulfonate (PS-PSS) in a mixture of ethanol and water (4/1, v/v). The obtained hybrid (PS-PSS)/C-dot nanoribbons show a multi-colored fluorescence and an electrical conductivity of 3.368 S m(-1).
