Preparation of organic amorphous film

Abstract

Abstract PURPOSE:To form a glass-like transparent amorphous film or turn an organic substance into a film by a dry method, by vapour depositing an organic substance while applying a light by means of vacuum vapour deposition method and preparing an organic amorphous film. CONSTITUTION:The temperature of a heating boat 17 is heated up to 170 deg.C by a heating temperature control device 18, and vacuum vapor deposition is carried out while 1',3',3'-trimethyl-6-nitrospiro[2H-1-benzopyran-2.2'-indoli-ne] (NBPS) in the sate of gas phase is irradiated with ultraviolet rays of 360nm bright line of a 500V super-high pressure mercury vapor lamp as an ultraviolet source under 1X10<-4>Torr degree of vacuum. At that time, NBPS is varied from the spiropyran type in the formula I to merocyanine type in the formula II. Further, as the same turns into a counter ion type and its polar characteristic is varied, crystallization is prevented, and as a result, a glass-like organic amorphous film can be prepared.
