We prepared different azadioxatriangulenium (ADOTA) and diazaoxatriangulenium (DAOTA) derivatives and thoroughly characterized their photophysical properties. We investigated their solvatochromic properties and the effects of the solvent, aided by computational chemistry results. The new ADOTA and DAOTA dyes were applied in multiple in cellulo microscopy modalities, including confocal, fluorescence lifetime imaging microscopy (FLIM), and super-resolution imaging. ADOTA derivatives predominantly accumulated in mitochondria, while DAOTAs showed pronounced nuclear staining and participation in endocytic pathways. Notably, these dyes enable clear discrimination of subcellular compartments via lifetime contrast in FLIM: mitochondria, where ADOTAs undergo electron transfer-driven quenching and display short lifetimes; nuclei and DNA, where lifetimes remain long; and endocytic vesicles, where partial dye aggregation leads to lifetime reduction.This work has been funded by grants PID2023-148243OB-I00 and PID2022-137214OB-C22 funded by MCIN/AEI/https://doi.org/10.13039/501100011033 and “ERDF A way of making Europe”, EU; grant PID2020-114256RB-I00 funded by AEI/https://doi.org/10.13039/501100011033; CSIC grant 202180E073; C.
