A library of fluorescent styryl dyes (320 compounds) was prepared by solid-phase chemistry. The dyes were screened for their detection of amyloid aggregates, which are associated with diseases such as Alzheimer's, and two of the 320 compounds screened, 2C40 and 2E10, showed promise as brain-imaging agents
