o-ICz-PI and p-ICz-PI (Figure ) were synthesized in one-pot via a synchronous palladiumcatalyzed Buchwald-Hartwig and Heck-coupling reaction pathway from previously reported bromine substituted di-tert-butylcarbazole and phthalimide precursors. Cz-PI (Figure ) was synthesized following similar conditions using unsubstituted di-tert-butylcarbazole via Buchwald-Hartwig coupling. 2-Ethylhexyl chains were attached to ensure good solubility of the molecules. Detailed synthetic procedures are given in the Supporting Information. All the molecules synthesized in this work were characterized by 1 H, C NMR spectroscopy and highresolution mass spectrometry (HRMS).
