• applications, including bio-imaging [6][7], drug and gene delivery [8], sensors [9][10], photocatalysis [11], energy storage [12][13] and white-light-emitting diodes (WLEDs) [14][15]. Typically, these materials contain an internal carbon core, conjugated sp2 domains and some functional groups attached to their
