White-light hyperbranched conjugated polymer, method for preparing the same and it's use
This application discloses a white-light hyperbranched conjugated polymer, a method for preparing the same and its use. The polymer uses a red phosphorescent Ir(III) complex as a core and polyfluorene derivative blue fluorescent materials as a framework which either contains or does not contain carbazole derivatives, and the white light hyperbranched polymers realize white-light emission by adjusting the content of the red phosphorescent Ir(III) complex connected using the complementation of blue and red color.

High mobility polymer organic field-effect transistors by blade-coating semiconductor:insulator blend solutions
Conjugated polymer-based organic field-effect transistors have garnered attention since the solution processability of the semiconductor material raises the possibility of lower device fabrication costs, and considerable progress has been made on achieving high mobility systems. Further improvements in charge carrier mobility while using non-specialized deposition techniques and minimizing the volume of semiconductor used in the fabrication process are important considerations for practical implementation. Here, a method of fabricating devices is disclosed that uses a technique (for example, a scalable blade-coating technique) to cast polymer thin film devices from blend solutions with one component being the polymer semiconductor and the other being a commodity polymer. Even when mixing the semiconducting polymer with 90% polystyrene by weight, an average mobility of 2.70.4 cm.sup.2 V.sup.1 s.sup.1 can be obtained.
