Liu, Kanglei;Lalancette, Roger A.;Jakle, Frieder research published 《 Tuning the Structure and Electronic Properties of B-N Fused Dipyridylanthracene and Implications on the Self-Sensitized Reactivity with Singlet Oxygen》, the research content is summarized as follows. We demonstrate that the modification of anthracene with B ← N Lewis pairs at their periphery serves as a highly effective tool to modify the electronic structure with important ramifications on the generation and reactivity toward singlet oxygen. A series of BN-fused dipyridylanthracenes with Me groups in different positions of the pyridyl ring have been prepared via directed electrophilic borylation. The steric and electronic effects of the substituents on the structural features and electronic properties of the isomeric borane-functionalized products have been investigated in detail, aided by exptl. tools and computational studies. We find that BDPA-2Me, with Me groups adjacent to the pyridyl N, has the longest B-N distance and shows overall less structural distortions, whereas BDPA-5Me with the Me group close to the anthracene backbone experiences severe distortions that are reflected in the buckling of the anthracene framework and dislocation of the boron atoms from the planes of the Ph rings they are attached to. The substitution pattern also has a dramatic effect on the self-sensitized reactivity of the acenes toward O2 and the thermal release of singlet oxygen from the resp. endoperoxides. Kinetic analyses reveal that BDPA-2Me rapidly reacts with O2, whereas BDPA-5Me is converted only very slowly to its endoperoxide. However, the latter serves as an effective singlet oxygen sensitizer, as demonstrated in the preferential formation of the endoperoxide of dimethylanthracene in a competition experiment These results demonstrate that even relatively small modifications in the substitution of the pyridyl ring of BN-fused dipyridylanthracenes change the steric and electronic structure, resulting in dramatically different reactivity patterns. Our findings provide important guidelines for the design of highly effective sensitizers for singlet oxygen on one hand and the realization of materials that readily form endoperoxides in a self-sensitized manner and then thermally release singlet oxygen on demand on the other hand.

Three boron-pyridyl-isoindoline-1-one based dyes (I: B1, B2, and B3) with varied side groups were facilely synthesized. Detailed analyses were carried out concerning the crystal conformation, structure dependent photophys. properties and mechanochromic fluorescence (MCF). The MCF behaviors and solid-state emission are correlated to the different side groups. Upon grinding, the emission of B1 exhibited little changes, whereas reversible MCF with a distinct color change was observed for B2 and B3. B3 possessing sterically hindered tri-Ph amine (TPA) groups showed the most prominent MCF effect. For instance, mech. grinding resulted in a red shift of fluorescence from 600 nm to 650 nm. The electronic and steric effects of the donating substituents play important roles in modulating the intramol. charge-transfer effect and intermol. interactions. These sensitively and readily tunable mechano-responsive behaviors of the boron-pyridyl-isoindoline-1-one based dyes make them potential candidates for smart fluorescent materials.

Lavagnino, Marissa N.;Liang, Tao;MacMillan, David W. C. research published 《 HARC as an open-shell strategy to bypass oxidative addition in Ullmann-Goldberg couplings》, the research content is summarized as follows. Herein, an alternative aryl halide activation strategy, in which the critical oxidative addition (OA) mechanism was replaced by a halogen abstraction-radical capture (HARC) sequence that allowed the generation of the Cu(III)-aryl intermediate albeit via a photoredox pathway was presented. This alternative mechanistic paradigm decoupled the bond-breaking and bond-forming steps of the catalytic cycle to enable the use of many previously inert aryl bromides. Overall, this mechanism allowed access to both traditional C-N adducts at room temperature as well as a large range of previously inaccessible Ullmann-Goldberg coupling products including sterically demanding ortho-substituted heteroarenes, e.g., I.
