This invention provides new electroluminescent materials such as a conjugated polymer or a phosphorescent organometallic complex, which are grafted with multiple charge transport moieties with graded ionization potential or electrophilic property. The charge transport moieties can be all hole transport moieties or all electron transport moieties. The emissive electroluminescent materials covering the full visible range can be prepared. Organic light emitting diodes prepared with these materials can be used as indicators, light source and display for cellular phones, digital camera, pager, portable computer, personal data acquisition (PDA), watch, hand-held videogame, and billboard, etc.
