Inside Back Cover: Transformation Pathway from CdSe Magic‐Size Clusters with Absorption Doublets at 373/393 nm to Clusters at 434/460 nm (Angew. Chem. Int. Ed. 37/2021)

Abstract

The transformation pathway … … for magic-size clusters (MSCs) with absorption doublets has remained unknown so far. Meng Zhang, Jianrong Zeng, Kui Yu et al. propose in their Research Article on page that the transformation from the MSCs with characteristic optical absorption at 373/393 nm (dMSC-393) to those at 433/460 nm (dMSC-460) occurs via the addition reaction of the CdSe monomers to the precursor compound of dMSC-393.

Revealing Two Distinct Formation Pathways of 2D Wurtzite‐CdSe Nanocrystals Using In Situ X‐Ray Scattering

“…Recently, in situ small‐angle X‐ray scattering (SAXS) has emerged as one of the most effective techniques for studying nanocrystal formation mechanism, because this nondestructive method can trace subnanometer spatial changes with a high temporal resolution of a few microseconds. [ 69 ] The formation mechanism and shape evolution of metal nanocrystals, [ 70 ] semiconductor nanocrystals, [ 55,56,71–73 ] and nanoclusters [ 60,74,75 ] have been extensively studied using SAXS. For 2D nanocrystals, in situ SAXS has been used to explore the lamellar templated growth of Cu 2‐ x S, [ 72 ] self‐assembly of CdSe–460‐nm clusters into cubic 2D nanoplatelets, [ 73 ] and lateral growth of cubic‐CdSe nanoplatelets.…”
