Bridging Chlorine Atoms Enable the Construction of a Novel ­Benzimidazole-Derived Fluorescent Molecule

Abstract

We have designed and prepared a novel benzimidazole-based fluorescent molecule through the construction of chlorine bridges. The structure of the molecule was authenticated by means of X-ray crystallography and its photophysical properties (absorption and fluorescence spectra) were investigated. Furthermore, the fluorescence emission of the molecule was rationalized through density functional theory calculations, which showed the influence of the bridging chlorine atoms on the energy levels and energy gap.

Key words

benzimidazoles - chlorine bridge - fluorescence - absorption - density functional theory

• 14 P1A 25 mL Schlenk flask equipped with a suitable stirrer bar was charged with 2-chlorobenzimidazole (1; 0.5 mmol) and n-hexylamine (2; 1.5 mmol), then capped with a rubber septum and subjected to three cycles of evacuation and backfilling with argon. The mixture was then heated at 120 ℃ for 16 h under argon. Finally, the product was directly purified by column chromatography [silica gel, CH₂Cl₂–MeOH (20:1)] to give a light-yellow solid; mp 134.5–135.4 ℃.¹H NMR (500 MHz, CDCl₃): δ = 12.06 (s, 1 H), 7.91 (s, 1 H), 7.43–7.28 (m, 2 H), 7.14–7.02 (m, 2 H), 3.57 (t, J = 6.7 Hz, 2 H), 1.67–1.57 (m, 2 H), 1.37–1.27 (m, 2 H), 1.18–1.09 (m, 4 H), 0.74 (t, J = 6.2 Hz, 3 H). ¹³C NMR (126 MHz, CDCl₃): δ = 154.9, 135.6, 121.2, 111.6, 43.5, 31.3, 29.7, 26.4, 22.4, 13.8.
