Key Points

The research aims to explore how the number and arrangement of aromatic rings affect the properties of phenanthro[9,10-d]imidazole derivatives for organic light-emitting diodes (OLEDs).
Synthesis of ten phenanthro[9,10-d]imidazole derivatives with varying C2 substituents.
Analysis of the relationship between the structure of derivatives and their OLED properties.
Findings indicate that both the number and arrangement of aromatic rings significantly influence the photophysical properties of the derivatives.
Certain substituent arrangements resulted in improved OLED performance metrics.

Abstract

This study investigates whether the number, arrangement, and attachment position of aromatic rings in C2 substituents influence the properties and OLED applicability of phenanthro9,10-dimidazole derivatives. We obtained ten derivatives via...
