Recently, carbon quantum dots (CQDs) as a fluorescent 0D carbon-based nanomaterial showing the fascinating optoelectrical properties and intrinsic non-toxicity to human bodies and environments have been triggered great research interests. Among the various synthetic protocols in order to synthesize highly fluorescent CQDs from numerous starting materials, microwave-assisted bottom-up synthesis of CQDs is very effective because diverse natural or synthetic ABx (x≥2) or Ax/By (x and y ≥2, x or y≥3) polyamidation monomer sets (A: -COOH, B: -NH2) could be exploited for the synthesis of functional CQDs with precise control of their surface functionalities and high optoelectrical performance. The formation of CQDs is regarded to progress through polycondensation (polyamidation) and carbonization of polyamidation monomer sets having ‘branching point’. Prepared functional CQDs have been examined in many promising applications including fluorescent bioimaging agents, fluorescent metal ion sensors, top-conversion layers on Si solar cells, etc. Through this recent advance, CQDs would be increasingly rivaling with the inorganic QDs in the near future applications.
