Cover Picture: Structural Engineering of Semiconductor Nanoparticles by Conjugated Interfacial Bonds (Chem. Rec. 1/2020)
Yi Peng, Qiming Liu, Shaowei Chen
Abstract
The cover picture shows the significance of interfacial bonding contact in manipulating the optical and electronic properties of semiconductor nanoparticles. Specifically, when the nanoparticles are functionalized with conjugated interfacial bonds, intraparticle charge delocalization occurs between the particle-bound functional moieties under select photoirradiation (“on” state). Such intraparticle charge transfer is impeded with a saturated interfacial linkage (“off” state). See the Personal Account by S. Chen et al. (DOI: 10.1002/tcr.201900010).
