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 organic light emitting diode, low in power consumption, high in luminance and long in service life. SOLUTION: This electroluminescent element includes a positive electrode 32, a negative electrode 42, and a luminescent layer 38. The luminescent layer 38 includes a self-gathering organic-inorganic hybrid material containing an organic portion and an inorganic portion. The organic portion includes a pigment emitting fluorescence in the visible region. To increase the fluorescence, the organic pigment portion can be partly replaced by an optically inactive component.

Abstract: PROBLEM TO BE SOLVED: To obtain a hybrid material which has a high luminescence strength by incorporating an inorganic component and an organic component containing a colorant component mixed with an optically inert component into the same. SOLUTION: Preferably, the organic component contains a colorant component which emits fluorescence in the visible region, preferable colorant components being e.g. tolan, thioxanthone, coumarin, and perylene. This hybrid material contains an inorganic component comprising a metal halide framework. Preferably, the content of the color component in the organic component is higher than 0% and lower than 10%. Examples of the inert material are phenethylamine, butyldiamine, and an alkylamine. The hybrid material has e.g. an organic - inorganic perovskite structure and is represented e.g. by the formula: (RNH3)2(NH3)n-1MnX3n+1 (wherein R is an organic group; M is a divalent metal; X is halogen; and (n) is 1 or higher).

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.

Abstract: An FET structure in accordance with the invention employs an organic-inorganic hybrid material as the semiconducting channel between source and drain electrodes of the device. The organic-inorganic material combines the advantages of an inorganic, crystalline solid with those of an organic material. The inorganic component forms an extended, inorganic one-, two-, or three-dimensional network to provide the high carrier mobilities characteristic of inorganic, crystalline solids. The organic component facilitates the self-assembly of these materials and enables the materials to be deposited by simple, low temperature processing conditions such as spin-coating, dip-coating, or thermal evaporation. The organic component is also used to tailor the electronic properties of the inorganic framework by defining the dimensionality of the inorganic component and the electronic coupling between inorganic units.

Abstract: PURPOSE: To provide an organic light emitting diode(OLED) having high operational stability and durability. CONSTITUTION: 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.
