We report the results of structural investigations on Langmuir(L)and Langmuir-Blodgett(LB)films of tetra-tert-butyl phthalocyanine(MTBPC)containing various transition metal ions.Techniques were developed for fabricating well-ordered L-monolayers using a flow-orientation method that dramatically enhances the molecular orientation of MTBPC in L-monolyers as compared to other techiques.The dilution procedure for developing solutions enables the formation of a well-defined single L-monolayer at the air-water interface.The tilt angles of MTBPCs in the L-monolayers are estimated by the limiting area technique.The tilting structure of LB films of MTBPCs on glass substrates as measured by X-ray diffraction(XRD)method is in good agreement with the estimate obtained by the limiting area technique on the corresponding L-monolayers.An annealing procedure significantly improves the ordering of the LB films as measured by XRD.
