| 英文摘要 | a synthesized blue fluorescent protein (bfp) chromophore analogue 2-bfp ((4z)-4-[(1h-imidazol-2-yl)methylene]-1-methyl-2-phenyl-1h-imidazol-5(4h)-one) displays dual fluorescent emission that arises from the same z-isomer. the larger stokes shift emission is a result of excited-state intramolecular proton transfer (esipt) mediated by an n-h center dot center dot center dot n type of hydrogen bond. compared to other green fluorescent protein (gfp) analogues with esipt such as o-hbdi, 2-bfp possesses greatly enhanced quantum yields and much slower proton-transfer rates. in addition, fluorescence up-conversion experiments revealed two rising components of lifetime for the tautomer formation of 2-bfp. the results imply that the relaxation of the n* state in 2-bfp triggers the proton transfer of the molecule. the weaker photoacidity of n-h is proposed to be crucial for these photophysical and photochemical properties. finally, the esipt process in 2-bfp is inhibited in protic solvents (meoh) or by the formation of metal chelate complexes, providing insights for further developments and applications of esipt molecules. |
