Intermolecular interactions in monolayers of porphyrins

Intermolecular interactions in monolayers of porphyrins.Some chemicals with cas registry numbers like 104937-02-2 and 5522-66-7 are also used.

DOCUMENT TYPE: Journal CA Section: 66 (Surface Chemistry and Colloids) Monolayers contg. solely porphyrins with or without aliph. chains or porphyrins mixed with phospholipids were studied on H2O and on solid surfaces. The systems were manipulated on the H2O surface and characterized by film balance techniques, fluorescence microscopy, fluorescence and absorption spectroscopy, and, after transfer onto solid supports, by optical and electron microscopy techniques. The data presented contain information on the interrelation between mol. and monolayer structure and on porphyrin-porphyrin and porphyrin-lipid interactions. Homogeneous monolayers can be formed only for porphyrins contg. aliph. chains or in diln. with lipids in the fluid phase. An ordered structure was obtained for Zn 3,8-bis(1'-heptadecenyl)deuteroporphyrin dimethyl ester (ZnHDPDME) that exhibits 2 aliph. chains attached to 1 edge and 2 (hydrophilic) ester groups to the opposite edge of the porphyrin moiety. If these groups are bound to the same edge, a disordered structure with little tendency to aggregate formation is obtained. None of the porphyrins are sol. in the solid phase of phospholipids. As this is presumably due to the high packing d. given by the area per hydrocarbon chain this is suggested to hold also for other aliph. matrixes including fatty acids. A strong decrease in fluorescence yield with increasing mol. d. is obsd. for ZnHDPDME dild. in phospholipids. This suggests a change in the coordination of the central Zn atom of the porphyrin. As the environment can be changed in a defined and continuous way these systems offer the possibility of studying the relation between the microscopic surroundings and the optical properties. .
