Investigation of the clear structure–property relationship and microscopic mechanism thermally activated delayed fluorescence (TADF) emitters with high emission quantum yield is a direction worthy continuous efforts. The instructive theoretical principle TADF material design critical challenging. Here, we carried out calculation on two experimental Cu(I) complexes same 7,8-bis(diphenylphosphino)-7,8-dicarba-nido-undecaborate (dppnc) but different N^N ligands [dmbpy =...

To overcome the disadvantages of primary bio-oil, two technical routes, namely, bio-oil ether extraction coupled with ether-soluble fraction microwave-assisted catalytic esterification (ES-MACE) and looped-oxide deoxygenation/mild electrocatalytic hydrogenation (MECH)/catalytic cracking to produce hydrocarbons, were conducted for upgrading. With first route, it was found that highest efficiency achieved when volume ratio bio-oil/ether 1:2 ES quality effectively improved in comparison...

Hypochlorous acid (HOCL) plays a critical role in the natural defense system, but excessive production of HOCL leads to many diseases. It is very essential monitor distribution and level endogenous HOCL. However, applicable two-photon-excited fluorescent (TPEF) phosphorescent probes for biological imaging quantitative detection rare due low efficiency vague mechanism. Therefore, we thoroughly researched electron structures luminous mechanisms turn-on ratiometric TPEF probe compounds provide...

Hypochloric acid (HOCl) plays a vital role in the natural defense system, but abnormal levels of it can cause cell damage, accelerated human aging, and various diseases. It is great significance to develop new probes for detecting HOCl biosystems nondestructively noninvasively. The purpose this work explore chemical modification strategies two-photon excitation fluorescence (TPEF) improve poor water solubility low efficiency imaging applications. Nil-OH-6 has absorption cross-section value...

Circularly polarized phosphorescent (CPP) materials, especially chiral platinum(II) complexes, which combine the advantages of both circularly luminescence (CPL) and phosphorescence, show broad potential applications in optoelectronic devices. Developing CPP emitters with excellent chiroptical properties high yield is urgently needed. Here, a cation strategy employed to construct Pt(II) complexes
