The effective imaging of amyloid β (Aβ) in vivo is important for the diagnosis of Aβ-related diseases such as the Alzheimer's disease (AD). Here we report a donor-acceptor-donor (D-A-D) type fluorogenic probe for the rapid imaging of amyloid β (Aβ) senile plaques in a transgenic mouse brain. The probe that features a dicyanomethylene-4H-pyran (DCM) core shows a concentration-dependent fluorescence
Preparation of 4-dicyanomethylene-2,6-distyryl-4H-pyran derivatives, their functional polystyrenes and study of their different aggregation induced emission behaviors
solid state red fluorescent materials with efficient light emission are rare but have wide applications in optoelectronic and biological fields. Herein, two pyran derivatives, EtAmPy and EtOxPy with different charge transfers (CT), were designed as initiators and introduced to polystyrene chains via atom transfer radical polymerization (ATRP). The emission of EtAmPy was quenched both in highly polar solvents
