The synthetic chemistry of colloidal nanocrystals (schematically depicted) could be environmentally benign and user friendly. This constraint encourages us to better understand crystallization phenomena in general.

Abstract

Green chemistry principles have gradually been implemented into the development of the synthetic chemistry of high-quality semiconductor nanocrystals.1, 2 In comparison with the original organometallic approach, the resulting alternative routes are safe, simple, inexpensive, reproducible, versatile, “user friendly”, and yield nanocrystals with well-controlled size, shape, and size/shape distribution. Further developments in this direction will promote the understanding of crystallization in general.
