Triazabutadiene molecules as cleavable cross-linkers adapted to cross-link components with dick chemistry, e.g., clickable triazabutadienes. For example, in some embodiments, the triazabutadienes feature alkyne handles attached to the imidazole portion or the aryl portion of the triazabutadienes, wherein the alkyne handles can link to azide handles (e.g., azide handles disposed on other components) via dick chemistry. Also described are methods of producing said clickable triazabutadienes and methods of use of said clickable triazabutadienes. The present invention also features methods of cleaving said clickable triazabutadienes, e.g., for liberating the diazonium species for further chemical reactions.

Protected triazabutadiene molecules, such as those according to Formula D or variations thereof, as probes for cellular studies in intact biological systems. The protected triazabutadiene probes selectively release benzene diazonium ions (BDIs) intracellularly, providing a tool for accessing and/or labeling intracellular proteins or molecules prior to cell lysis. The present invention also includes methods for synthesizing the protected triazabutadienes, the protected triazabutadienes themselves, and methods of use.
