Benzimidazole is a benzo derivative of imidazole. It is a kind of bicyclic aromatic organic compounds, which is formed by fusing a six-membered benzene ring and five-membered imidazole at positions 4 and 5 of imidazole ring. It is an important pharmacophore of many biologically active heterocyclic compounds with various pharmacological activities. Benzimidazoles and their derivatives have developed into dynamic heterocyclic systems due to their potency in a variety of biologically active compounds such as anticancer, bactericidal and antiviral drugs. Benzimidazoles are a class of therapeutic motifs with broad relevance in medicinal chemistry.
Organic light emitting diodes (devices) or OLEDs are monolithic solid-state devices that typically consist of a series of organic thin films sandwiched between two thin film conductive electrodes. It is a display technology used in many electronic devices, such as smartphones, televisions, and wearables. In an OLED display, each pixel is made up of organic compounds that emit light when an electric current passes through them. Unlike traditional LCD displays, this eliminates the need for a backlight. As a result, OLED displays can achieve deeper blacks and higher contrast ratios, leading to vibrant and more realistic images.
