Harada, Naoyuki; Sasaki, Yoichi; Hosoyamada, Masanori; Kimizuka, Nobuo; Yanai, Nobuhiro published the article 《Discovery of Key TIPS-Naphthalene for Efficient Visible-to-UV Photon Upconversion under Sunlight and Room Light**》. Keywords: discovery key TIPS naphthalene efficient visible UV photon upconversion; LED; TIPS-naphthalene; UV light; photon upconversion; triplet-triplet annihilation.They researched the compound: 2,5-Diphenyloxazole( cas:92-71-7 ).Quality Control of 2,5-Diphenyloxazole. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:92-71-7) here.
While many studies have been done on triplet-triplet annihilation-based photon upconversion (TTA-UC) to produce visible light with high efficiency, the efficient TTA-UC from visible to UV light, despite its importance for a variety of solar and indoor applications, remains a challenging task. Here, we report the highest visible-to-UV TTA-UC efficiency of 20.5 % based on the discovery of an excellent UV emitter, 1,4-bis((triisopropylsilyl)ethynyl)naphthalene (TIPS-Nph). TIPS-Nph is an acceptor with desirable features of high fluorescence quantum yield and high singlet generation efficiency by TTA. TIPS-Nph has a low enough triplet energy level to be sensitized by Ir(C6)2(acac), a superior donor that does not quench UV emission. The combination of TIPS-Nph and Ir(C6)2(acac) realizes the efficient UV light production even with weak light sources such as an AM 1.5 solar simulator and room LEDs.
This literature about this compound(92-71-7)Quality Control of 2,5-Diphenyloxazolehas given us a lot of inspiration, and I hope that the research on this compound(2,5-Diphenyloxazole) can be further advanced. Maybe we can get more compounds in a similar way.
