Abstract
Optical force probes (OFPs) are force-responsive molecules that report on mechanically induced transformations by the alteration of their optical properties. Yet, their modular design and incorporation into polymer architectures at desired positions is challenging. Here we report triazole-extended anthracene OFPs that combine two modular ‘click’ reactions in their synthesis potentially allowing their incorporation at desirable positions in complex polymer materials. Importantly, these retain the excellent optical properties of their parent 9-π-extended anthracene OFP counterparts.

- 29 Synthesis of OFP diol 2 Mechanophore precursor 1 (549 mg, 1.6 mmol, 1.00 equiv) and 3-azido-1-propanol (155 μL, 1.68 mmol, 1.05 equiv) were dissolved in a mixture of THF (20 mL) and water (6 mL). Sodium l-ascorbate (317 mg, 1.6 mmol, 1.00 equiv) was added, followed by CuIISO4·5H2O (40 mg, 0.16 mmol, 0.100 equiv). The heterogeneous mixture was stirred vigorously at rt overnight and was afterwards diluted with water (50 mL). THF was removed in vacuo, and the white precipitate was cooled in an ice bath before collection by filtration. After washing the precipitate with cold water (2 ( 25 mL), it was dried in vacuo to yield the triazole mechanophore diol 2 (70% yield) as white solid. 1H NMR (400 MHz, DMSO-d 6): δ = 8.54 (s, 1 H), 7.52 (dd, J = 7.4, 1.2 Hz, 1 H), 7.41 (dd, J = 6.8, 1.9 Hz, 1 H), 7.30 (dd, J = 6.5, 2.0 Hz, 1 H), 7.18 (qt, J = 5.6, 2.6 Hz, 3 H), 7.04 (td, J = 7.6, 1.3 Hz, 1 H), 6.26 (d, J = 7.6 Hz, 1 H), 4.85 (d, J = 3.1 Hz, 1 H), 4.75 (t, J = 5.1 Hz, 1 H), 4.63 (t, J = 7.0 Hz, 2 H), 4.59 (t, J = 5.9 Hz, 1 H), 3.90 (d, J = 8.3 Hz, 1 H), 3.53 (dt, J = 7.6, 6.0 Hz, 2 H), 3.38 (dd, J = 8.3, 3.1 Hz, 1 H), 2.95 (ddt, J = 13.0, 9.2, 4.7 Hz, 2 H), 2.64–2.41 (m, 2 H), 2.12 (p, J = 6.7 Hz, 2 H); see Figure S1. 13C NMR (101 MHz, DMSO-d 6): δ = 175.94, 174.94, 144.29, 143.10, 141.00, 139.27, 138.42, 126.58, 126.56, 126.17, 126.15, 125.93, 124.82, 124.30, 123.80, 123.67, 57.49, 56.34, 49.23, 48.09, 47.50, 46.76, 44.89, 33.10; see Figure S2.
