Abstract:
The invention relates to a phthalocyanine compound, which has a structure as represented by Formula I, wherein A represents a transition metal or a rare earth metal; R1 represents a phenyl group, a naphthyl group, or a C4-C16 n-alkyl group. The aromatic phthalocyanine compound having the structure of Formula I provided in the invention contains a transition metal or a rare earth metal, and introduces a peripheral substituent into a linearly extended 7c-conjugated system. It is relatively stabler at 400° C. or less and will be easily evaporated in vacuum to form a uniform thin film, and has good thermal stability, high chemical stability, and high mobility. The organic semiconductor device has the features of relatively fast on-off speed, relatively high on-off ratio, and strong reliability.
Abstract:
The present invention relates to the field of organic electroluminescent technology, particularly relates to an aromatic amine derivative, its preparation method, uses and organic electroluminescent devices. The technical aim of the present invention is to improve the film forming ability and the redox repeatability. The aromatic amine derivative has the structure of formula I, wherein, R1, R2, R3 and R4 each independently represent a hydrogen, a substituted or unsubstituted C1-C40 alkyl, a substituted or unsubstituted C1-C40 alkoxy, a substituted or unsubstituted C3-C40 cycloalkyl, a substituted or unsubstituted C6-C50 aryl group, a substituted or unsubstituted C3-C50 heteroaryl containing one or two heteroatoms selected from N, O and S, or a substituted or unsubstituted C10-C40 fused aryl group formed together with the phenyl group linked therewith; wherein, m, n, p and q each independently represent 0, 1, 2, 3, 4 or 5; the substituents are one or more groups selected from the group consisting of a halogen, a C1-C10 alkyl, a C1-C10 alkoxy, a C3-C20 cycloalkyl, a C6-C20 aryl group or a C4-C20 heteroaryl group. The present invention may be applied in organic electroluminescent devices.
Abstract:
The present invention discloses a plant selling device and a control method thereof, by which a ripe plant to be sold can be moved from a plant growth room to a sales room according to the information in a purchase order after the purchase order is generated. According to the technical solution of the present invention, plant factory technology can be combined effectively with automatic plant selling so that plants are sold automatically after ripening, thus providing a more convenient mode of production and sale.
