Abstract: PROBLEM TO BE SOLVED: To obtain the subject element capable of exhibiting an excellent hole transport performance between a cathode and a hole transport layer and an excellent endurance, and useful as a flat panel display by providing a hole injection layer between the cathode and the hole transport layer. SOLUTION: This organic electroluminescent element holding by nipping an organic electric field light emitting layer containing a hole transport layer between a cathode and an anode, is obtained by providing a hole injection layer e.g. a layer consisting of a compound of the formula (M is a metal, preferably Ge, Sn, Pb, As and At) or a halogen salt thereof and having 0.5-10nm layer thickness. Thus, it is possible to improve the close adherence in a boundary of the cathode and the hole transport layer for improving a hole injection efficiency, and also prevent a diffusion of oxygen and an adsorbed water from the cathode into the hole transport layer on heat generation by the element, for capable of preventing a deterioration of a hole transport material.

Abstract: PURPOSE:To highly accurately discriminate an organic gas by using a Langmuir Blodgett(LB) film made of a long-chain amine compound as a gas sensitive film. CONSTITUTION:The oscillation of a gas sensitive element 3 is transmitted to a frequency counter 4 through a distributor 12 after noise is cut off by means of a filter 11 and the counter 4 measures the oscillating frequency of the element 3, finds the variation of the oscillating frequency caused by gas adsorption based on the measured frequency, and discriminates an organic gas by comparing the variation with a standard pattern. When an LB film composed of a Y-type four-layer laminated film of a longchain amine compound, for example, l-docosylamine is used as the gas sensitive film of the element 3, the adsorptivity of the element 3 is diversified and organic gases can be discriminated with high accuracy. Especially, the element 3 can discriminate organic gases even when the gases are of alkaline substances, because the gases are not irreversibly absorbed by the LB film.
