Abstract: Strong photoinduced oxidants are important to organic synthesis and solar energy conversion, to chemical fuels or electric. For these applications, visible light absorption is important to solar energy conversion and long-lived excited states are needed to drive catalysis. With respect to these desirable qualities, a series of five 5,6-dicyano[2,1,3]benzothiadiazole (DCBT) dyes are examined as organic chromophores that can serve as strong photooxidants in catalytic systems. The series utilizes a DCBT core with aryl groups on the periphery with varying electron donation strengths relative to the core. The dyes are studied via both steady-state and transient absorption and emission studies. Additionally, computational analysis, voltammetry, crystallography, and absorption spectroelectrochemistry are also used to better understand the behavior of these dyes. Ultimately, a strong photooxidant is arrived at with an exceptionally long excited state lifetime for an organic chromophore of 16 µs. The long-lived excited state photosensitizer is well-suited for use in catalysis, and visible light driven photosensitized water oxidation is demonstrated using a water-soluble photosensitizer.

YieldReaction ConditionsOperation in experiment
57% With dichloro(1,1'-bis(diphenylphosphanyl)ferrocene)palladium(II)*CH2Cl2; potassium carbonate; In dichloromethane; water; at 60℃; General procedure: All liquids incorporated into the reaction were degassed prior to addition. To a solution of 1 (1 eq., 50.0 mg, 0.192 mmols) and PdCl2(dppf)•CH2Cl2 (20 mol%, 31.3 mg, 0.0384 mmols) in CH2Cl2 (0.1M, 1.6 mL) was added aryl bromide (1.1 eq., 0.211 mmols) and 3.33M K2CO3 solution (6 eq.,0.958 mmols, 0.27 mL). The mixture is quickly stirred and heated at 60. The mixture would go from a bright red solution to a darkened mixture within minutes of the reaction. Upon confirmation of completion by TLC (typically eluted with 40% to 50% MeCN/CH2Cl2), the mixture is immediately taken off the heat and diluted with 10 mL H2O. The organic mixture is extracted with 3 x 10 mL diethyl ether. The organic extracts are dried over Na2SO4, filtered then concentrated. The crude product is purified by silica gel column chromatography (gradient with ethylacetate/hexanes) to afford 3 as a resin or white powder.
