Synthesis of two new zinc porphyrin fluorescein dyads are reported here. The two chromophoric units are covalently linked by alkane or alkyne bond, which provides various degrees of flexibility. Conformational analysis as photophysical properties were performed both experimentally (NOESY experiments, lifetimes, ROS production…) and theoretically (DFT and TD‐DFT calculations). Comparison with triazole linker described in a precedent study highlighted that linkage nature determine conformational structure (folding/linearity) but do not significantly modify energy transfer between the two moieties involved in dyads.
