The synthesis of pentacene and tetracene bridged dimers with 𝛽 = 14Ph, 26N, and 26A have been previously reported. Similar cross-coupling conditions are used to synthesize 𝛽 = 13Ph, 27N, 15N, 16N, and 27A, as detailed in the SI. We note that TIPS (triisopropylsilylethynyl) groups are installed on all anthracene, tetracene, and pentacene chromophores for solubility and stability.
