Title:
ELECTRONIC DEVICE, ORGANIC ELECTROLUMINESCENT ELEMENT, ORGANIC THIN-FILM SOLAR CELL, AND DYE-SENSITIZED SOLAR CELL
Document Type and Number:
WIPO Patent Application WO/2014/189072
Kind Code:
A1
Abstract:
This invention addresses the problem of providing an electronic device, organic electroluminescent element, conductive film, organic thin-film solar cell, and dye-sensitized solar cell provided with a charge-transporting thin film that exhibits excellent stability. In the presence of external disturbances, said charge-transporting thin film exhibits little in the way of fluctuations, and the resistance of said charge-transporting thin film changes little over time as current is supplied. As one of the secondary effects thereof, said charge-transporting thin film results in little in the way of changes in emission characteristics over time. This electronic device, which is provided with a charge-transporting thin film that contains one or more functional organic compounds having chirality-creating sites, is characterized by the provision of a charge-transporting thin film wherein the per-molecule counts of said chirality-creating sites, summed over all of the aforementioned functional organic compounds, total at least 4.
