Photocontrol of Electrical Conductance with a Nonsymmetrical Azobenzene Dithiol

Abstract

We report a method for preparing electrode–molecule–electrode junctions that incorporate nonsymmetrical azobenzene dithiols. Our approach is based on sequential deprotection of thiol moieties originally carrying two different protecting groups. The azobenzene derivatives retained their switching properties within monolayers and permitted the photocontrol of electrical conductance.

Key words

azo compounds - thiols - protecting groups - self-assembly - isomerization

• 21 S-{3-[(4-Hydroxyphenyl)diazenyl]phenyl} Ethanethioate (7) In a round-bottomed flask, disulfide 4 (306 mg; 1.5 mmol) was dissolved in H₂O (3 mL). 1.0 M aq HCl (3.3 mL) was added, and the mixture was cooled to 0 °C. In a separate flask, a solution of NaNO₂ (108 mg; 1.56 mmol) in H₂O (5 mL) was cooled to 0 °C. The cold NaNO₂ solution was then added at once to the cooled solution of disulfide 4. The resulting mixture was stirred for 5 min at 0 °C and then added dropwise to a solution of PhOH (149 mg; 1.58 mmol) and NaOAc (247 mg; 3.01 mmol) in H₂O (5 mL) cooled to 0 °C. After the addition was completed, the mixture was stirred for an additional 5 h at 0 °C. The ice bath was then removed, and the mixture was stirred for an additional 14 h at r.t. The resulting yellow precipitate was collected by filtration, dried under reduced pressure, and purified by column chromatography (silica gel, 5% EtOAc–CH₂Cl₂) to give a brownish solid; yield: 222 mg (54%). ¹H NMR (300 MHz, CDCl₃): δ = 7.93–7.89 (m, 2 H), 7.82 (d, J = 8.9 Hz, 2 H), 7.58–7.46 (m, 2 H), 6.88 (d, J = 8.9 Hz, 2 H), 5.59 (s, 1 H), 2.48 (s, 3 H). ¹³C NMR (125 MHz, CDCl₃): δ = 194.77, 159.15, 152.75, 146.59, 136.02, 129.84, 128.71, 127.95, 125.43 (2 C), 124.32, 115.91 (2 C), 30.32.

Alcohol 3 (115 mg; 0.21 mmol) and KI (5 mg) were then added, and the mixture was stirred at 60 °C for 12 h. The mixture was then cooled to r.t. and H₂O (50 mL) was added. The yellow precipitate that formed was extracted into CH₂Cl₂ (3 × 20 mL). The organic phase was washed with water (3 × 20 mL), dried (MgSO₄), and concentrated under reduced pressure to give a yellow solid.
