Chlorophyll derivatives possessing a BF 2 diketonate group at the C3 position were synthesized. Their electronic absorption spectra showed red‐shifted Q and broadened Soret bands, which based on DFT calculations were ascribed to the interaction between the LUMO orbitals of chlorin and BF 2 diketonate group. The synthetic chlorophyll derivative substituted with a pyrenyl group at the terminal position of diketonate group gave a charge‐transfer band at around 500 nm, enhancing the light absorption ability.
