Higher order structure and laser photochemical processes of molecular associate systems have been studied by means of fluorescence single photon counting, laser photolysis, and photocurrent measurements. Absorption as well as fluorescence spectra and conformational dynamics of bis[1-(2-pyrenyl)ethyl]-ether excimers, a stability of mono- and multi-layer films of 1-octa-decanethiol, and photoinduced electron transfer of organic single crystals covered by LB filmof anthrylalkane were elucidated in detail.
