The photocuring efficiency of a photoinitiator is increased by mixing it with an organic phosphite and an aldehyde. This mixture or photoinitiator composition can be used to cure acrylates or other photocurable compounds, particularly in an oxygen-containing environment.
摘要:
An organic semiconducting composition consists essentially of an N,N-dicycloalkyl-substituted naphthalene diimide and a polymer additive comprising an insulating or semiconducting polymer having a permittivity at 1000 Hz of at least 1.5 and up to and including 5. This composition can be used to provide a semiconducting layer in a thin-film transistor that can be incorporated into a variety of electronic devices.
摘要:
An amic acid or amic ester precursor can be applied to a substrate and thermally converted into a thin organic semiconducting layer of the corresponding arylene diimide. This semiconducting layer can be used in various semiconductive articles such as organic light emitting diode (OLED), photodetector, sensor, logic circuit, memory element, capacitor, photovoltaic (PV) cell, or electronic devices. In this manner, the arylene diimide need not be coated but is generated in situ from a solvent-soluble and easily coated precursor compound.

A thin film transistor comprises a layer of organic semiconductor material comprising a configurationally controlled N,N′-dicycloalkyl-substituted naphthalene-1,4,5,8-bis-carboximide compound having a substituted or unsubstituted alicyclic ring independently attached to each imide nitrogen atom with the proviso that at least one of the two alicyclic rings is necessarily a 4-substituted cyclohexyl ring in which a substituent at the 4-position is the sole substituent on the 4-substituted cyclohexyl ring other than the imide attachment; with such substituent being stereochemically disposed as only one of either an essentially trans or cis position, respectively, to the imide nitrogen substituent. Such transistors can further comprise spaced apart first and second contact means or electrodes in contact with said material. Further disclosed is a process for fabricating an organic thin-film transistor device, preferably by sublimation deposition onto a substrate, wherein the substrate temperature is no more than 100° C.
