Abstract

Luminogenic bioorthogonal probes have emerged as very useful tools to visualize biomolecules in complex cellular environments through “turn-on” emission and high selectivity toward unique functional groups that minimize the background luminescence of unreacted reagents. Recently, there has been a strong focus on the design of luminogenic bioorthogonal probes that rely on the emission quenching effect of the tetrazine moiety. Herein, we report the synthesis, characterization, and photophysical studies of three novel luminogenic cyclometalated iridium(III) bis-tetrazine complexes. The applications of these complexes as luminogenic double-clicking two-point binders for the derivatives of a strained alkyne, bicyclo[6.1.0]non-4-yne (BCN) were examined. The cellular uptake efficiency and (photo)cytotoxicity of the complexes were also studied by ICP-MS and MTT assays, respectively.
