Wasielewski, M. R.

The following topics are discussed: preparation of covalently bound dimeric species of chlorophyll; molecular structure of bis(bacteriochlorophyllide a) ethylene glycol diester; /sup 1/H spectra of BChl, a covalent dimer, dissolved in various solvents; chemical shift changes in proton resonances; C/sub 2/ symmetric folded configuration of covalently linked BChl; electronic transition spectrum of Chl a covalent dimer in dry CCl/sub 4/ and in water-saturated CCl/sub 4/; special pair models of bis(chlorophyll) cyclophanes; synthetic pathway for preparation of bis(chlorophyll) cyclophane 8; proton magnetic resonance data; redox potentials of chlorophyll; and optical and EPR properties of special pairs.
