Larger VH (Hole Distribution Volume)/VM (Molecular Volume) Induced Higher Charge Mobility of Group IVA Element-Based Host Materials for Potentially Highly Efficient Blue OLEDs
The Journal of Physical Chemistry C, 2018Co-Authors: Chuang Yao, Cheng Peng, Yezi Yang, Jinshan WangAbstract:Host materials have a decisive effect on the optoelectronic properties of organic light-emitting diodes (OLEDs), whether for fluorescent, phosphorescent, or thermally actIVAted delayed fluorescence OLEDs. In this work, we first conducted a comprehensive investigation of Group IVA Element-based small molecular host materials (DCzC, DCzSi, DCzGe, DCzSn, and DCzPb). A multiscale simulation was used to investigate the electronic properties of these materials. The results reflected a novel phenomenon; that is, the hole-transport mobility of DCzC is larger than those of the other Group IVA Element-based hole-transport materials, which indicated that, compared with the already existing Si-tetraphenyl and Ge-tetraphenyl, the C-tetraphenyl has a higher potential to act as the core moiety to construct high-performance host materials. DCzC has the best hole-transport properties because it has a smaller molecular volume (VM) while keeping the hole distribution volume (VH) unchanged, compared with those of the other m...

Group IVA Element si ge sn based alloying dealloying anodes as negative electrodes for full cell lithium ion batteries
Small, 2017Co-Authors: X Li, Qi Wang, Yujun Fu, Deyan HeAbstract:To satisfy the increasing energy demands of portable electronics, electric vehicles, and miniaturized energy storage devices, improvements to lithium-ion batteries (LIBs) are required to provide higher energy/power densities and longer cycle lives. Group IVA Element (Si, Ge, Sn)-based alloying/dealloying anodes are promising candidates for use as electrodes in next-generation LIBs owing to their extremely high gravimetric and volumetric capacities, low working voltages, and natural abundances. However, due to the violent volume changes that occur during lithium-ion insertion/extraction and the formation of an unstable solid electrolyte interface, the use of Group IVA Element-based anodes in commercial LIBs is still a great challenge. Evaluating the electrochemical performance of an anode in a full-cell configuration is a key step in investigating the possible application of the active material in LIBs. In this regard, the recent progress and important approaches to overcoming and alleviating the drawbacks of Group IVA Element-based anode materials are reviewed, such as the severe volume variations during cycling and the relatively brittle electrode/electrolyte interface in full-cell LIBs. Finally, perspectives and future challenges in achieving the practical application of Group IVA Element-based anodes in high-energy and high-power-density LIB systems are proposed.
