| Abstract: | —Enzyme-generated triplet acetone and triplet indole-3-aldehyde transfer energy very efficiently to chloroplasts, as indicated by the intensity of the sensitized red emission that is observed. The intermediacy of excited species of oxygen (1O2, O2−, HO) has been excluded. Our results open the way for investigating energy transfer in architecturally organized systems in the absence of light. |
