Abstract: The disclosure relates to the technical field of preparation of circularly polarized luminescence materials, in particular to a central chirality induced helical chiral tetradentate cyclometalated platinum (II) complex, an electronic device and application thereof. The central chirality induced helical chiral tetradentate cyclometalated platinum (II) complex provided in the disclosure has a general structure as shown in formula (I) or (I?) in which (I) and (I?) are enantiomers to each other: Helical chiral metal complex molecules can autonomously induce a whole tetradentate ligand to coordinate with metal ions in a less sterically hindered manner by means of a central chiral fragment La in the tetradentate ligand, to form an optically pure helical chiral metal complex-based circularly polarized luminescence material, without need for chiral resolution. Moreover, the material has high chemical stability and thermal stability, and has important applications in circularly polarized luminescence elements.

Abstract: A method and a device for rapidly editing sending content based on a receiver. A sending-content-learning module is used to learn sending content to generate a content fragment for a receiver, and perform word frequency statistics on the content fragment; a corresponding list is generated from receiver information, the content fragment, and the word frequency statistics, and is stored; for the receiver and the word frequency statistics, the content fragment is displayed for a sender to edit the sending content, so as to send the sending content to a corresponding receiver. When a user edits a short message or an email, a content fragment commonly used for a corresponding receiver is displayed in a display box, and a sender can rapidly complete editing by selecting a required content fragment, thereby facilitating fast and convenient input and improving the user experience.

Abstract: A multi-touch supporting parallel-tapping input method comprising the following steps: obtaining multiple input operations of a user at the same time; converting the input operations of the user into characters, permuting and combining the characters, and selecting a correct character combination sequence; displaying the selected character combination sequence as a candidate character sequence in a candidate display unit for the user to select; and displaying the character combination sequence selected by the user. The method may be implemented using a multi-touch supporting virtual keyboard, so that multiple fingers can select multiple keys at the same time to perform parallel-tapping input. Through intelligent error correction, multiple keys tapped in parallel are permutated and combined to provide a candidate correct combination for a user to select, so as to improve the speed and efficiency of text inputting of the user.

Abstract: A method for rapid data classification comprises selecting a data queue in which data with the same type is arranged adjacently. A starting point pointer, a middle point pointer, and an ending point pointer are enabled to point to a starting point, a middle point, and an ending point of the data queue, respectively. The method further comprises determining whether the types of the data pointed to by the starting point pointer and the middle point pointer are the same, and classifying the data with one type. The method further comprises enabling the starting point pointer to point to a starting position of a next type of the data, determining whether the types of the data pointed to by the starting point pointer and the middle point pointer are the same, and classifying the next type of data.

Abstract: A system that facilitates targeted advertising is described in detail herein. The system includes a receiver component that receives user data that includes historical searching and browsing activity of a user. A profile generator component generates a user profile based at least in part upon a subset of the user data, wherein the user profile includes a plurality of keywords, wherein at least one keyword in the plurality of keywords is assigned a score that is indicative of a probability that an advertisement corresponding to the keyword will be monetized.
