Energy-transducing membrane : II. Roles of liquid crystal in the photoresponse of a chlorophyll liquid crystal membrane.

M Aizawa1, M Hirano, S Suzuki.   

Abstract

The states of chlorophyll a (Chl a) incorporated in a liquid crystal membrane were investigated by spectrophotometry in the visible and IR regions.N-(p-methoxybenzylidene)-p'-butylaniline (MBBA) was used as the liquid crystal. The Chl a-MBBA (1∶3 in molar ratio) showed the dihydrate-Chl a aggregate peak at 743 nm under excess water conditions. IR spectroscopic evidence indicated that the Chl a-MBBA membrane was hydrated in the dihydrate stoichiometry [Chl a-3MBBA-2H2O], via the C-10 ester OC…H(H)O…Mg and the C-9 keto OC…H(H)O…Mg bondings.
