Neutral branched platinum-acetylide complex possessing a tetraphenylethylene core: preparation of luminescent organometallic gelator and its unexpected spectroscopic behaviour during sol-to-gel transition

27.08.2015 | Yuan-Yuan Ren; Nai-Wei Wu; Junhai Huang; Zheng Xu; Dan-Dan Sun; Cui-Hong Wang; Lin Xu, Chemical Communication, 2015

A neutral branched platinum-acetylide complex TPA possessing a tetraphenylethylene core was successfully prepared, which was found to form luminescent organometallic gels in ethyl acetate. Stimulited by temperature or F-, the reversible gel-sol transition was realized. More interestingly, TPA ...

Nonaqueous Redox-Flow Batteries: Organic Solvents, Supporting Electrolytes, and Redox Pairs

26.08.2015 | Ke Gong; Qianrong Fang; Shuang Gu; S F Y Li; Yushan Yan, Energy & Environmental Science, 2015

As a family member of redox-flow batteries (RFBs), nonaqueous RFBs can offer wide working temperature, high cell voltage, and potentially high energy density. These key features make nonaqueous RFBs an important complement of aqueous RFBs, broadening the spectrum of RFB applications. The ...
