Maeda, Chihiro Masuda, Mikako Yoshioka, Naoki Effective π‑Extension of Carbazole-Based Thiaporphyrins by Peripheral Phenylethynyl Substituents Several tetrakis(phenylethynyl)- and (phenylethynylphenylethynyl)-substituted carbazole-based thiaporphyrins were synthesized. These π-extended porphyrins display remarkably intensified and red-shifted absorption bands in the NIR region up to 1126 nm due to perturbation by the phenylethynyl substituents.
