Organic Chemistry - Introduction 1 2812 Basic definitions for organic chemistry Scope Organic chemistry is a vast subject so it is easier to split it into small sections for study. This is usually done by studying compounds which behave in a similar way because they have a particular atom‚ or group of atoms‚ (FUNCTIONAL GROUP) in their structure. Catenation The ability to form bonds between atoms of the same element. Carbon catenates to form chains and rings‚ with single‚ double

Application of Organic Light Emitting Diode (OLED) for Display Systems: Advanced Characteristics and Possible Solutions to Challenges 1. Introduction The first organic light emitting diode (OLED)‚ which was an innovatory of electroluminescence that emits light using organic materials‚ was reported in 1987 (Tang & VanSlyke‚ 1987). OLED displays are constructed by surrounding a glass or plastic substrate with organic compounds that emit light when current passes through them (Askari‚ 2014). Continuous
