Smart near-infrared fluorescence probes with donor-acceptor structure for in vivo detection of β-amyloid deposits

The deposition of β-amyloid (Aβ) plaques in the parenchymal and cortical brain is accepted as the main pathological hallmark of Alzheimer's disease (AD); however, early detection of AD still presents a challenge. With the assistance of molecular imaging t

Non-linear optically active molecules, their synthesis, and use

In one aspect, the present invention provides a hyperpolarizable organic chromophore. The chromophore is a nonlinear optically active compound that includes a π-donor conjugated to a π-acceptor through a π-electron conjugated bridge. In other aspects of the invention, donor structures and acceptor structures are provided. In another aspect of the invention, a chromophore-containing polymer is provided. In one embodiment, the chromophore is physically incorporated into the polymer to provide a composite. In another embodiment, the chromophore is covalently bonded to the polymer, either as a side chain polymer or through crosslinking into the polymer. In other aspects, the present invention also provides a method for making the chromophore, a method for making the chromophore-containing polymer, and methods for using the chromophore and chromophore-containing polymer.

Cyanovinylheteroaromatics for Organic Nonlinear Optics

Effects of various substituents including chromophores on the second harmonic generation (SHG) of cyanovinylheteroaromatics were examined.The molecular polarizability was calculated by the PPP MO method to correlate SHG responsiveness with chemical structures. 3-indole 8b exhibited good SHG efficiency (PE = 25U).The X-ray analysis of 8b showed that the crystals belong to novel and the most favorable P1 space group.
