Abstract
Abstract— Multilayer Langmuir‐Blodgett films of chlorophyll u and chlorophyll a in L‐α‐phosphatidylcholine dipal‐mitoyl matrix have been prepared. The films were protected by covering them with eight layers of stearic acid to ensure high film stability during the light illumination. Based on the time‐resolved fluorescence measurements a model with two types of chlorophyll arrangement was developed. One arrangement could be attributed to an aggregated state and the other to a homogeneously distributed state. Transient absorption in the wavelength range from 380 and 740 nm and the time range from 0.1 to 100 μs were measured. The chlorophyll a radicals and the triplet state were observed and their lifetimes estimated.
