  • Artificial Light-Harvesting Antennae: Singlet Excitation Energy Transfer from Zinc Chlorin Aggregate to Bacteriochlorin in Homogeneous Hexane Solution

    singlet excitation energy transfer from the zinc chlorin aggregate to the bacteriochlorin moiety of the coaggre‐gated dyad occurs in the homogeneous solution. In the coaggregated dyad, the bacteriochlorin moiety plays the role of an efficient energy trap and the chlorin moiety the role of an anchor to the donor aggregate. The artificial assembly thus mimics the structure and function of natural chlorosomes

Comparison of the equilibrium constant in a zinc chlorin with those of the corresponding zinc bacteriochlorin (7,8-dihydrochlorin) and porphyrin (17,18-dedihydrochlorin) led to an increase in the saturation and flexibility of the tetrapyrrole pi-plane ligands making the central zinc more axial-ligated.

  • Q<i><sub>y</sub></i>-Excitation Resonance Raman Spectra of Chlorophyll <i>a</i> and Related Complexes. Normal Mode Characteristics of the Low-Frequency Vibrations
    作者:Chengli Zhou、James R. Diers、David F. Bocian
    DOI:10.1021/jp971965g
    日期:1997.11.1
    Q(y)-excitation resonance Raman (RR) spectra are reported for film aggregates of chlorophyll (Chi) a and a series of related complexes. The latter include Mg(II) octaethylporphyrin (MgOEP), Mg(II) trans-octaethylchlorin (MgOEC), methyl-9-desoxomesopyrochlorophyllide (DMPChl) a, and methylpyrochlorophyllide (MPChl) a. These complexes represent a series in which the structural complexities of Chl a (saturated pyrrole ring, isocyclic ring, C-9-keto group, C-2-vinyl group, and C-10-carbomethoxy group) are systematically added to the basic tetrapyrrole architecture. On the basis of comparison of the RR scattering characteristics of the different complexes and the predictions of semiempirical normal coordinate calculations, a self-consistent set of vibrational assignments has been developed for all the RR active modes in the low-frequency regime (100-1000 cm(-1)). The studies indicate that the low-frequency Vibrations encompass a diverse set of motions that include both the ring skeleton and peripheral substituent groups. However, modes in the very low-frequency regime (<250 cm(-1)) are primarily due to deformations of the substituent groups. Collectively, the normal mode characteristics of Chi a and the other Mg(II) complexes provide insights into the nature of the vibrational modes that are coupled to the photophysically important, lowest energy excited states of natural photosynthetic assemblies.
