Abstract: The aggregation behavior of some cholesterol esters in ethylene glycol monoether/watet mixed solvent has been studied preliminarily in this work. Result indicates that this mixed solvent possesses good ability for promoting aggregate formation. The formation of excimer of naphthalene can be observed clearly while the aggregation of cholesterol ester occurs. The process of photoinduced electron-transfer and the formation of exciplex can also be observed while the two cholesterol esters, which were used as electronic donor and acceptor respectively, were aggregated together.

Key words: cholesterol esters, aggregation, excimer, electron transfer, exciplex
