A poly(p-phenylene) (PPP) containing rhodamine 6G (R6G) was synthesized by the Suzuki-coupling reaction, in which PPP acted as a blue-emitting energy donor and R6G acted as a ligand for Fe(iii) as well as the energy acceptor for Förster resonance energy transfer.

A conventional fluorescence microscope was modified to observe the sites of resonance energy transfer (RET) between fluorescent probes in model membranes and in living cells. These modifications, and the parameters necessary to observe RET between membrane-bound fluorochromes, are detailed for a system that uses N-4-nitrobenzo-2-oxa-1,3-diazole (NBD) or fluorescein as the energy donor and sulforhodamine as the energy acceptor. The necessary parameters for RET in this system were first optimized using liposomes. Both quenching of the energy donor and sensitized fluorescence of the energy acceptor could be directly observed in the microscope. RET microscopy was then used in cultured fibroblasts to identify those intracellular organelles labeled by the lipid probe, N-SRh-decylamine (N-SRh-C10). This was done by observing the sites of RET in cells doubly labeled with N-SRh-C10 and an NBD-labeled lipid previously shown to label the endoplasmic reticulum, mitochondria, and nuclear envelope. RET microscopy was also used in cells treated with fluorescein-labeled Lens culinaris agglutinin and a sulforhodamine derivative of phosphatidylcholine to examine the internalization of plasma membrane lipid and protein probes. After internalization, the fluorescent lectin resided in most, but not all of the intracellular compartments labeled by the fluorescent lipid, suggesting sorting of the membrane-bound lectin into a subset of internal compartments. We conclude that RET microscopy can co-localize different membrane-bound components at high resolution, and may be particularly useful in examining temporal and spatial changes in the distribution of fluorescent molecules in membranes of the living cell.

Lanthanide-based resonance energy transfer (LRET) is an established method for measuring or detecting proximity between a luminescent lanthanide (energy donor) and an organic fluorophore (energy acceptor). Because resonance energy transfer is a distance-dependent phenomenon that increases in efficiency to the 6th power of the distance between the donor and the acceptor, assay systems are often designed to minimize donor-acceptor distances. However, the authors show that because of the R6 relationship between transfer efficiency and sensitized emission lifetime, energy transfer can be difficult to measure in a time-gated manner when the donor-acceptor distance is small relative to the Förster radius. In such systems, the advantages inherent in time-resolved, ratiometric measurements are lost but can be regained by designing the system such that the average donor-acceptor distance is increased.
