Abstract: The reactions of DMF/POCl3 with 1,5-diphenylpyrazoline,1,3,5-triphenylpyrazoline and l,5-diphenyl-3-styrylpyrazoline respectively afford three anticipated formylated compounds,which condense with l-hydroxyethyl-2,3,3-trimethyl-3H-indolium iodide,then are treated with base to give IVa,IVb and IVc,which have not been found in literature.The primary experiments show that the arylpyrazolinyl styryloxazolidino [3,2-a]dihydroindoles have halochromic and piezochromic property.The properties make them suitable for manufacturing the acid-sensitive film and using as the pressure-sensitive pigment.

Key words: Pyrazoline, Oxazolidino[3,2-a]dihydroindole, Halochromism, Piezochromism
