Two-Dimensional Graphitic Carbon Nitride for Improving the Performance of Organic Solar Cells.

Organic solar cells (OSCs) have attracted lots of attention owing to their low cost, lightweight, and flexibility properties. Nowadays, the performance of OSCs is continuously improving with the development of active layer materials. However, the traditional hole transport layer (HTL) material Poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) presents insufficient conductivity and rapid degradation, which decreases the efficiency and stability of OSCs.

Fluorescence detection of protamine, heparin and heparinase II based on a novel AIE molecule with four carboxyl.

In this research, a new DSA (Distyryl-anthracene) derivative with four carboxyl groups was designed and synthesized. This molecule exhibits aggregation-induced emission property (AIE). With the AIE character, a convenient and sensitive fluorescent probe for the detection of protamine, heparin and heparinase has been developed.
