Material or material of main part are applied in optics or electro-optical device, including photosensitive device, Organic Light Emitting Diode, light emitting devices and energy
The device of enough compatible light absorption and transmitting.As shown in table 2, using BO1 and BO2 as the absolute quantum of the thin-film device of material of main part
Efficiency is above 80%, and the high efficiency energy for illustrating to have occurred main body to guest materials under excitation state shifts, at the same show BO1 and
BO2 is feasible as Blue-light emitting host material.An effective solution way is provided for Blue-light emitting host material in short supply at present
Diameter, to push the development in this field significantly.
It will be understood by those skilled in the art that the respective embodiments described above are to realize specific embodiments of the present invention,
And in practical applications, can to it, various changes can be made in the form and details, without departing from the spirit and scope of the present invention.
For example, many materials and structure described herein can use other materials and knot without departing substantially from spirit of the invention
Structure replaces.
