    • 3 The initial polydispersity index of 13 was 1.2, and all spectra were recorded at that purity level. Preparative TLC on a portion was used to sharpen the index to 1.06.

    • The overall yields of the final 17-mer 13 was determined by comparing the loading of the monomer 1 on the polymer support (compound 5) and the yield of the final oligomer when liberated from the polymer support: 5 (10.0 g, 4.8 mmol of loading of 1) → 6 (10.5 g) → 7 (10.3 g) → 8 (13.9 g) of which only a 7.2% mass portion (1.00 g) was taken on in the polymer-supported form → 9 (1.03 g) → 10 (0.98 g) → 12 (1.30 g) → 13 (0.31 g, 0.069 mmol). Starting from 4.8 mmol of 1 in 5 and using only 7.2% mass of the material during the conversion of 8 → 9, gives a theoretical yield of 0.35 mmol and an actual yield of 0.069 mmol (20%) for 13.
