Abstract

We report a simple two-step method for the synthesis of a novel highly fluorescent benzothiophene-based dye comprising five fused rings and exhibiting a large Stokes shift (Δλ = 152 nm or Δν = 5482 cm^–1 in ethanol). Structural features of the obtained compound allow easy functionalization of the carbon core and open new possibility for the development of a series of new classes of fluorescent dyes.

Key words

fluorescence - benzothiophenes - fluorescent dye - Stokes shift - oxidative coupling

11 Typical Procedure for the Synthesis of Methyl 6,7-Dimethoxybenzo[b]thiophene-3-carboxylate (2)To the solution of thiol 1 (2.60 g, 15.27 mmol) in acetonitrile (150 mL) methyl propiolate (2.7 mL, 30.54 mmol) and AIBN (0.50 g, 3.1 mmol) were added under argon atmosphere. A yellow solution was stirred for 2 h under reflux. Liquids were evaporated in vacuo to obtain a yellow oil. The crude product was purified by column chromatography on silica gel (hexane–EtOAc from 50:1 to 15:1) to obtain 2 (1.35 g, 5.4 mmol, 35%) as colorless needles; R_f = 0.57 (hexane–EtOAc = 7:3).Analytical Data for 2 ¹H NMR (300 MHz, CDCl₃): δ = 8.25 (1 H, d, J = 8.6 Hz), 8.22 (1 H, s), 7.18 (1 H, d, J = 8.9 Hz), 4.03 (3 H, s), 3.96 (3 H, s), 3.93 (3 H, s). ¹³C NMR (75 MHz, CDCl₃): δ = 163.4, 148.9, 142.9, 135.4, 134.8, 132.2, 127.3, 120.1, 113.8, 60.7, 57.0, 51.8.

13 Synthesis of 1-Methoxycarbonyl-4,5,9,10-tetramethoxy-6-oxo-6H-phenantro[6,5-b:1,10-b′c′]dithiophene (3)A mixture of compound 2 (50.0 mg, 0.198 mmol), FeCl₃ (64.3 mg, 0.396 mmol), and DCE (0.5 mL) was stirred in a sealed tube under argon atmosphere for 2 h at 85 °С. After cooling to r.t. 1 M HCl (3 mL) was added, and the mixture was extracted with DCM (3 × 2 mL). Combined organic layers were washed with water (3 × 2 mL), brine (3 × 2 mL), dried over Na₂SO₄, and evaporated under reduced pressure. The residue was purified by flash column chromatography (hexane–EtOAc = 7:3) to obtain 3 as an orange solid (45 mg, 0.096 mmol, 97%). R_f = 0.35 (hexane–EtOAc = 7:3).Analytical Data for 3 ¹H NMR (300 MHz, CDCl₃): δ = 8.55 (1 H, s), 8.23 (1 H, s), 7.40 (1 H, s), 4.18 (3 H, s), 4.15 (3 H, s), 4.05 (3 H, s), 3.96 (3 H, s), 3.56 (3 H, s). ¹³C NMR (75 MHz, CDCl₃): δ = 179.5, 165.3, 150.9, 149.4, 147.1, 144.6, 141.4, 136.2, 135.1, 132.9, 132.8, 131.6, 131.0, 129.7, 128.4, 127.6, 122.7, 113.1, 62.0, 61.4, 61.0, 57.2, 52.2.
