摘要:
A method of regioselectively preparing a pyridine-containing compound is provided. In particular embodiments, the method includes reacting halogen-functionalized pyridal[2,1,3]thiadiazole with organotin-functionalized cyclopenta[2,1-b:3,4-b′]dithiophene or organotin-functionalized indaceno[1,2-b:5,6-b′]dithiophene. Also provided is a method of preparing a polymer. The method includes regioselectively preparing a monomer that includes a pyridal[2,1,3]thiadiazole unit; and reacting the monomer to produce a polymer that includes a regioregular conjugated backbone section, wherein the section includes a repeat unit containing the pyridal[2,1,3]thiadiazole unit. A polymer that includes a regioregular conjugated backbone section, and electronic devices that include the polymer, are also provided.

A method and system for updating searches on an online auction site are described. In one embodiment, a database of auction postings is automatically searched based upon at least one search criteria to produce at least one new search result. The at least one new search result is compared with at least one previous search result. In addition, an e-mail notification of the result of the comparison is sent to a user notifying a user of the comparison.

A method and system for automatically updating searches are described. In one embodiment, a first search result may be compared with a second search result to automatically identify from the first search result at least one data item that is new or modified as compared to the second search result. The first search result may comprise a first set of data items satisfying a first set of user-specific search criteria, and the second search result may comprise a second set of data items satisfying a second set of user-specific search criteria. A notification of a result of the comparing may be sent to a user device.

A method and system for automatically updating searches are described. In one embodiment, a first search result may be compared with a second search result to automatically identify at least one data item within the first search result that is changed relative to the second search result. The at least one data item may comprise a transaction term. A notification of the at least one data item may be transmitted to a user device.

A method and apparatus for verifying identity of a participant in a network-based transaction facility are described. According to one embodiment, user interface information is provided to the participant via a communications network. The user interface information specifies an identity verification interface for obtaining personal information of the participant. The personal information of the participant is passed to a third party for verification via the communications network. Subsequently, a verification result is received from the third party via the communications network. The verification result is then communicated to the participant via the communications network.
