Probing the Surface Structure of Amine/Chloride-Passivated CdSe Nanocrystals Using Dynamic Nuclear Polarization-Enhanced 15N, 35Cl, 77Se, and 113Cd Solid-State NMR Spectroscopy
Ligands have been extensively used to modulate and improve the photophysical properties of nanocrystals (NCs). However, the surface structure of many NCs remains unknown. In this study, we synthesized oleate-capped CdSe NCs, exchanged them with oleylamine/CdCl2, and used dynamic nuclear polarization (DNP)-enhanced solid-state NMR spectroscopy to determine the structure of surface Cd atoms bound to ligands. 113Cd and 77Se NMR experiments distinguish different types of 113Cd and 77Se environments in the CdSe NCs. DNP-enhanced 113Cd magic angle turning (MAT) experiments enable the identification of one bulk and two surface Cd environments in CdSe NCs, while DNP-enhanced 15N{1H} and 15N{113Cd} heteronuclear correlation experiments reveal nitrogen coordinated Cd atoms on the surface of the CdSe NCs. Indirect detection of chloride ligands was achieved using DNP-enhanced 113Cd{35Cl} J-resolved experiments, revealing that the chlorides bridge between surface Cd atoms. Comparing the experimental NMR spectra to relativistic density functional theory calculation models establishes two distinct surface Cd environments that differ by their ligand environments: one site is coordinated by one amine and a bridging chloride, while the other is coordinated by two amines.

Excited that Md Pavel's recent work on the phase selective synthesis of alkali triel chalcogenide nanocrystals has been selected as a HOT article in @jmaterchem.bsky.social

My quote of the day

As I reflect on my life, I recognize that our greatest achievements often arise from our most profound struggles. Embrace challenges and view failures as opportunities for growth. It is through these trials that we learn, adapt, and ultimately succeed.
