Two alkyl fluorene-based cross-linkable hole transport materials with high triplet energies were designed and synthesized, providing a simple molecular design strategy for constructing efficient solution-processed PHOLEDs.
Chiral bipolar hosts of (R/S)-L-2mCPCN are synthesized, which show high S1/T1 energy levels and clear circularly polarized luminescence. Solution-processable CP-OLEDs based on such chiral hosts were achieved via a chirality energy transfer process.
Two chiral hosts, named (R/S)-BN-mCP and (R/S)-BN-2mCP, are prepared. The solution processable CP-OLED based on chiral host and achiral phosphorescent emitter presents the best performance with an EQEmax of 17.1% and the gEL of﹣1.3 × 10−3.
The impedance spectroscopy analysis is utilized to probe the modifications of charge carrier dynamics arising from interface mixing in a solution-processed organic light emitting diode.
The deep interconnection between nucleic acids and carbohydrates has prompted numerous synthetic campaigns to understand nucleic acid etiology, develop orthogonal genetic systems, and improve the properties of therapeutic oligonucleotides.
