Effective π-Extension of Carbazole-Based Thiaporphyrins by Peripheral Phenylethynyl Substituents
摘要:
Several tetrakis(phenylethynyl)- and (phenylethynylphenylethynyl)-substituted carbazole-based thiaporphyrins were synthesized. These pi-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.
