Various styrylbenzene compounds were synthesized and evaluated as mainly Aβ amyloid sensors. These compounds, however, cannot be used for detecting amyloid deposition in peripheral nerves because of the inherent sensitivity of the compounds. These compounds often generate false positives especially...
