A wavelength-orthogonal photocleavable monochromophoric linker was developed that is based on a 3-acetyl-9-ethyl-6-methylcarbazole (AEMC) moiety substituted at both the phenacyl and benzylic positions with different carboxylic acids. The different carboxylic acids were released sequentially upon irradiation with light of λ ≥ 365 nm and λ ≥ 290 nm, respectively.
