摘要：

Chlorophyll a was adsorbed to freeze-dried montmorillonite, bentonite, in benzene to form chlorophyll-bentonite conjugate. The adsorption proceeds into two steps; monolayer and multilayer adsorption. The absorption maximum in red region of chlorophyll a shifts to longer wavelength from 660 nm to 678 nm by increasing the amount of chlorophyll a conjugated with bentonite. Chlorophylls in the conjugated state was found to be photo-stable, although chlorophylls free from bentonite took place the marked bleaching by light-illumination.
