Abstract: PROBLEM TO BE SOLVED: To provide an organic light emitting diode(OLED) having high operational stability and durability. SOLUTION: In the present invention, a neutral dyestuff molecule (D) is converted to an ionic salt (DA+X-DA-X+), and then used as a luminous layer or charge transfer layer in OLED. This is realized by combining an ionezable substituent (A) with dyestuff molecule in the first synthesizing step, and then reacting it with a suitable reagent including ion (X) which balances the electric charge. The ionic compound can be attached as amorphous film using a conventional vapor deposition technique. In addition, these are thermally stable against crystallization. The OLED device in which the light emitting layer is made of such a dyestuff salt has higher efficiency and durability compared with a device using a neutral dyestuff molecule.

Abstract: PROBLEM TO BE SOLVED: To provide an FET structure which uses an organic/inorganic by hybrid material as a semiconductor channel. SOLUTION: This FET structure uses an organic/inorganic hybrid material 32 as a semiconductor channel between a source electrode 34 and a drain electrode 36 in a device. The organic/inorganic material has advantages of an inorganic crystalline solid and an organic material. The inorganic element forms an extended inorganic one-dimensional, two-dimensional or three- dimensional network, and provides a high carrier mobility for an inorganic crystalline solid. The organic element promotes self assembly of these materials and permits adhesion of the materials under conditions of simple low- temperature treatment such as spin coating, dipping coating, thermal vapor- deposition, etc. In addition, the organic element is used to adjust the electronic characteristics of inorganic skeleton, by defining the dimension of the inorganic element and the electronic bonding between inorganic units.
