Three new xanthone derivatives, 3-(4-(diphenylamino)-9H-carbazol-9-yl)-9H-xanthen-9-one (XanCarDipha), 2-(4-(4-(diphenylamino)-9H-carbazol-9-yl)phenyl)-9H-xanthen-9-one (p-XanCarDipha), and 2-(3-(4-(diphenylamino)-9H-carbazol-9-yl)phenyl)-9H-xanthen-9-one (m-XanCarDipha) as host materials are designed and synthesized, and they are applied to the development of green phosphorescent organic light-emitting diodes (PHOLEDs). Due to the different connection methods of carbazole units and xanthone units of the compounds, the efficiency curves of XanCarDipha exhibited significantly difference compared to other two materials after above three new materials are made into OLED devices as single host in emitting layer (EML). In EML, a PHOLED using 1: 1 p-XanCarDipha: CarTria as double host and doped with 12 wt% tris(2-phenylpyridine) iridium as a guest material can achieve the uppermost external quantum efficiency (EQE) of 20.93%, the uppermost current efficiency (CE) of 77.40 cd A?1, and the uppermost power efficiency (PE) of 93.15 lm W?1. Compared with corresponding highest luminous efficiency of devices using p-XanCarDipha as single host material (16.86%, 62.55 cd A?1 and 42.60 lm W?1), the efficiency of double-host materials has been significantly enhanced. Meanwhile, the glass transition temperatures (Tg) of the three new host materials are all higher than 120 C, indicating that they should have good thermal stability in the device application. This work not only provides a design direction for xanthones, but also demonstrates its superior performance on OLED devices when they combined with another host material.

An intramolecular dearomatization of indole derivatives based on visible-light-promoted [2+2] cycloaddition was achieved via energy transfer mechanism. The highly strained cyclobutane-fused angular tetracyclic spiroindolines, which were typically unattainable under thermal conditions, could be directly accessed in high yields (up to 99%) with excellent diastereoselectivity (>20:1 dr) under mild conditions. The method was also compatible with diverse functional groups and amenable to flexible transformations. In addition, DFT calculations provided guidance on the rational design of substrates and deep understanding of the reaction pathways. This process constituted a rare example of indole functionalization by exploiting visible-light-induced reactivity at the excited states.

A visible-light-promoted C(sp3)-H amidation and chlorination of N-chlorosulfonamides (NCSs) is reported. This remote C(sp3)-H functionalization can be achieved in weak basic solution at room temperature with as little as 0.1 mol % of a photocatalyst. A variety of nitrogen-containing heterocycles (up to 94% yield) and chlorides (up to 93% yield) are prepared from NCSs. Late-stage C(sp3)-H functionalization of complex and biologically important (-)-cis-myrtanylamine and (+)-dehydroabietylamine derivatives can also be achieved with excellent yields and regioselectivity.

Here we present a detailed kinetic study of the multisite proton-coupled electron transfer (MS-PCET) activations of aryl ketones using a variety of Br°nsted acids and excited-state Ir(III)-based electron donors. A simple method is described for simultaneously extracting both the hydrogen-bonding equilibrium constants and the rate constants for the PCET event from deconvolution of the luminescence quenching data. These experiments confirm that these activations occur in a concerted fashion, wherein the proton and electron are transferred to the ketone substrate in a single elementary step. The rates constants for the PCET events were linearly correlated with their driving forces over a range of nearly 19 kcal/mol. However, the slope of the rate-driving force relationship deviated significantly from expectations based on Marcus theory. A rationalization for this observation is proposed based on the principle of non-perfect synchronization, wherein factors that serve to stabilize the product are only partially realized at the transition state. A discussion of the relevance of these findings to the applications of MS-PCET in organic synthesis is also presented.

Cyclometalated iridium(iii) complexes have been prepared in high yields from base-assisted transmetalation reactions of cis-bis(aquo)iridium(iii) complexes with boronated aromatic proligands. Reactions proceed at room temperature. Potassium hydroxide and potassium phosphate are effective supporting bases. Kinetic, meridional isomers are isolated because of the mildness of the new technique. Syntheses are faster with KOH, but the gentler base K3PO4 broadens the reaction’s scope. Complexes of chelated ketone, aldehyde, and alcohol complexes are reported that bind iridium through formally neutral oxygen and formally anionic carbon. The new complexes luminesce with microsecond-scale lifetimes at 77 K and nanosecond-scale lifetimes at room temperature; emission quenches in air. Two complexes, an aldehyde and its reduced (alcohol) derivative, are crystallographically characterized. Their bonding is examined with density-functional theory calculations. Time-dependent computations suggest that the Franck-Condon triplet states of these complexes have mixed orbital parentage, arising from one-particle transitions that mingle through configuration interaction.
