Organic mixed valence compounds with N,N-dihydrodimethylphenazine redox centres

The mixed-valence character of four bis(N,N-dihydrodimethylphenazine) radical cation derivatives with varying π-electron bridges was investigated. The electron transfer (ET) distance within these derivatives varies from ca. 12.5 A? for 1,2-bis[2-(5,10-dihydro-5,10-dimethylphenazinyl)]acetylene (1) to ca. 19.3 A? for 9,10-bis[2-(5,10-dihydro-5,10-dimethylphenazinyl)ethynyl]anthracene (4). All radical cation species show intense intervalence charge-transfer (IV-CT) bands in the NIR. The Mulliken-Hush analysis was used to derive the electronic coupling V, which ranges from 310 to 870 cm-1. Comparisons with analogous ET systems in which the dihydrodimethylphenazine redox centres have been replaced by triarylamine units show that the dihydrodimethylphenazine species have a significantly higher internal reorganisation energy associated with the ET. This behaviour is attributed to C-N stretching and C-C ring modes of the dihydrodimethylphenazine units.

Synthesis of Cyclobutadienoid-Fused Phenazines with Strongly Modulated Degrees of Antiaromaticity

The streamlined synthesis of a series of regioisomeric azaacene analogues containing fused phenazine and antiaromatic cyclobutadienoids (CBDs), using a catalytic arene-oxanorbornene annulation, followed by aromatization is reported. Controlling the fusion patterns allowed strong modulation of local antiaromaticity. Enhancing antiaromaticity in these regioisomeric azaacenes led to stabilized LUMO, reduced band gap, and quenched fluorescence. This synthetic strategy provides a facile means to fuse CBDs with variable degrees of antiaromaticity onto N-heteroarenes to tune their optoelectronic properties.

An umpolung strategy for rapid access to thermally activated delayed fluorescence (TADF) materials based on phenazine

Herein, Ag(I)-promoted regioselective intramolecular radical nucleophilic addition/rearrangement of 2-aryl diazaboroles has been accomplished for the first time to construct phenazine structures. This protocol is an umpolung strategy based on the classical electrophilic mechanism, and therefore, a reversed regioselectivity was observed, which provides an opportunity to prepare sterically hindered phenazines. The resulting thermally activated delayed fluorescence (TADF) materials based on phenazine exhibit emission bands from green to red with high quantum yields and moderate fluorescence lifetimes as solid films.

The silver-mediated annulation of arylcarbamic acids and nitrosoarenes toward phenazines

A silver-mediated annulation between arylcarbamic acids and nitrosoarenes was developed, leading to phenazines in moderate to good yields with complexity and diversity. This procedure proceeded with the sequential ortho[sbnd] C[sbnd]H functionalization of arylcarbamic acids, insertion to nitroso group and decarboxylative annulation.

Preparation method of phenazine compound

To the method, a phenazine compound is prepared through continuous ortho C-H functionalization, nitroso insertion and decarboxylation processes of aryl carbamic acid, wherein a carboxyl amino group serves as a trace-free positioning group.

Cu-Catalyzed π-Core Evolution of Benzoxadiazoles with Diaryliodonium Salts for Regioselective Synthesis of Phenazine Scaffolds

The Cu-catalyzed regioselective synthesis of phenazine N-oxides was realized from benzoxadiazoles and diaryliodonium salts. The process was initiated by the electrophilic arylation of benzoxadiazoles with diaryliodonium salts and followed by benzocyclization reactions. The further reduction of N-oxides in situ to phenazine scaffolds and deviation to organic fluorescent materials were readily accomplished.
