演 題：Purely organic electroluminescent materials and devices
講演概要：Organic electroluminescence devices constructed with purely organic luminescent materials
without noble metals can greatly reduce the material cost of the devices, simplify the device structure,
and reduce the processing cost of the devices to a greater extent. This presentation will introduce
our research progress in the modulation of the horizontal dipole orientation and the excited state of
purely organic luminescent materials and their applications in organic electroluminescent devices.
By fine-tuning the molecular structure, molecular conformation, aggregated state structure and
thus the excited state behavior, and rapid intersystem crossing rate and radiative transition utilization
of triplet excitons as well as high efficiency organic fluorescence and phosphorescence devices are realized.
