A series of natural chlorins with octadecylamine residue in pyrrole rings A and D have been prepared on the basis of chlorophyll a derivatives. The compounds are capable to form intermolecular conjugates with upconversion nanoparticles (UCNP) due to hydrophobic interactions with oleic acid on the surface of nanocrystals. Coincidence of the intensive chlorin absorption band with UCNP fluorescence in red range of spectrum results in Förster resonance energy transfer (FRET).
