Thermally activated delayed fluorescence material for locking triphenylphosphine oxide receptor based on ether bond conformation

The invention discloses a thermally activated delayed fluorescence material for locking a triphenylphosphine oxide receptor based on ether bond conformation. The material has a structure as shown in aformula which is described in the specification. The thermally activated delayed fluorescence material has very good blue light or green light color purity, very high luminous quantum efficiency andcharge injection/transmission performance, and is applicable as a luminescent material for preparation of a high-performance organic electroluminescent device; in addition, the blue light-emitting material also has a very high excited state energy level, and can be used as a host material for preparing a high-performance organic light-emitting device.

Asymmetric thermally activated delayed fluorescence (TADF) emitters with 5,9-dioxa-13: B -boranaphtho[3,2,1- de] anthracene (OBA) as the acceptor and highly efficient blue-emitting OLEDs

A series of new organic emitters was prepared by introducing various donors (Ds) to the meta-position of the boron atom in the central phenyl ring in the acceptor (A) of 5,9-dioxa-13b-boranaphtho[3,2,1-de]anthracene (OBA). Moreover, their thermal, photophysical, electrochemical and electroluminescent (EL) properties were characterized in detail. The photophysical results revealed that these OBA-based molecules adopted a D-A configuration and exhibited efficient thermally activated delayed fluorescence (TADF) properties with a reverse inter-system crossing constant (kRISC) in the order of 105 s-1. It has been shown that introducing the -Br group to the OBA acceptor could increase kRISC by 2 to 3 times. Importantly, the deep-blue TADF emitter OBA-O showed a high photoluminescent quantum yield (PLQY) of 0.84, while its blue analog OBA-BrO with the -Br group exhibited an even higher PLQY of 0.92 in the doped film state. Benefitting from their high PLQYs as blue-emitting TADF emitters, the doped organic light-emitting diodes (OLEDs) based on these OBA-based TADF emitters exhibited attractive electroluminescent (EL) performances. The blue-emitting OLEDs with CIE (0.17, 0.17) showed the maximum external quantum efficiency (ηext) of 17.8%, current efficiency (ηL) of 33.2 cd A-1 and power efficiency (ηP) of 34.2 lm W-1, while that for the bluish-green device were 22.5%, 49.2 cd A-1 and 56.9 lm W-1, respectively. Thus, the great potential of these TADF emitter-based OBA acceptors was clearly demonstrated by their EL data. In addition, these asymmetric OBA-based molecules will enrich the structural diversity of this type of TADF emitter.

Interface Engineering in Two-Dimensional Heterostructures: Towards an Advanced Catalyst for Ullmann Couplings

The design of advanced catalysts for organic reactions is of profound significance. During such processes, electrophilicity and nucleophilicity play vital roles in the activation of chemical bonds and ultimately speed up organic reactions. Herein, we demonstrate a new way to regulate the electro- and nucleophilicity of catalysts for organic transformations. Interface engineering in two-dimensional heteronanostructures triggered electron transfer across the interface. The catalyst was thus rendered more electropositive, which led to superior performance in Ullmann reactions. In the presence of the engineered 2D Cu2S/MoS2 heteronanostructure, the coupling of iodobenzene and para-chlorophenol gave the desired product in 92 % yield under mild conditions (100 °C). Furthermore, the catalyst exhibited excellent stability as well as high recyclability with a yield of 89 % after five cycles. We propose that interface engineering could be widely employed for the development of new catalysts for organic reactions.

FLAME RETARDANT HALOGENATED PHENYL ETHERS

A halogenated non-polymeric phenyl ether is described having the general formula (I): wherein each X is independently Cl or Br, n is an integer of 1 or 2, each m is independently an integer of 1 to 5 and each p is independently an integer of 1 to 4, provided that, when X is Cl, the total amount halogen in the ether is from about 50 to about 65 wt% and when, X is Br, the total amount halogen in the ether is from at least 70 wt % to about 79 wt%.

Ligand-free highly effective iron/copper co-catalyzed formation of dimeric aryl ethers or sulfides

Highly selective coupling of diiodoarenes with phenols or phenthiols can be performed by using a low-cost, benign character and readily available Fe/Cu catalytic system in the absence of ligands. It is noteworthy that the desired dimeric aryl ethers or sulfides could be obtained in high yields by coupling between diiodoarenes and phenols, or diphenols with aryl iodides.

Bis(cyclopentadienyliron)arene Complexes: A new route to the synthesis and functionalization of polyaromatic ethers

A new development in the chemistry of arenes activated toward SNAr reactions by the cyclopentadienyliron (FeCp+) moiety is presented in this work. A class of diiron complexes of diphenoxybenzenes was prepared in a highly efficient and very mild fashion. Dihydroxy aromatic compounds served as dinucleophiles, allowing for the formation of the diiron complexes. This could be achieved in either a one or two step procedure. A wide variety of dinucleophiles were incorporated into this study, as well as a number of FeCp+ activated arenes. It is shown that these reactions are not inhibited by bulky substituents on either the dinucleophiles or activated arenes. The diiron complexes themselves could also undergo SNAr reactions, provided that the complexed arenes contained a chlorine substituent. This allowed for the functionalization of the complexes with species that could not be introduced directly in their syntheses. The carbon nucleophiles generated from ethyl cyanoacetate or (phenylsulfonyl)acetonitrile could be attached to the complexed ethers in this manner. The FeCp+ moieties were removed easily by photolytic demetalation which allowed for the recovery of a wide range of functionalized diphenoxybenzenes. This methodology is advantageous over all those previously reported and should be a practical route to the synthesis of aromatic ethers.
