Abstract: The title phthalocyanine derivative is easily soluble in chloroform.Electron spectro-scopy showed that the molecules in dilute chloroform solution and LB film therefromobtained were in monomolecular and associated state respectively.The monolayers of the title compound spread from the chloroform solution were depo-sited on solid supports by LB technique according to the Z-type.The surface pressure ofthe film was near 25mN.m-1.The chemiresistors prepared from 30-layer LB films of thetitle compound were sensitive to NH3 gas at concentration of 2ppm with good selectivity.

Key words: phthaloeyanine derivative, NH3 sensibility, LB film, synthesis
