报告题目：Complex p-conjugated architectures: From molecular design to OLED applications
报告时间：15:00 PM, Oct. 25th (Wednesday)
Organic electronics have imposed a strong demand on π-conjugated molecules and the synthesis of new materials with specific properties is strongly developed worldwide. Regioisomerism, also called positional isomerism, is an important concept in organic chemistry which can have remarkable consequences on the properties of molecules. Indeed, a simple structural modification can drastically influence the electronic and physical properties of an organic semi-conductor (OSC), which in turn strongly modifies the performance and stability of the corresponding electronic device. Although very promising, this concept remains nevertheless rarely used in optoelectronics. Herein, we will investigate the impact of regioisomerism to finely tune the singlet and triplet energies of different classes of materials, from dihydroindenofluorene to fluorenes isomers, leading to highly efficient optoelectronic devices. Different molecular designs of high triplet energy hosts incorporating various electron withdrawing and/or electron donating fragments for high performance green and blue Phosphorescent OLEDs will be presented.
