- Synthesis and Characterization of swallow-tail Terrylene Bisimide as Red Organic Phosphor for Hybrid LED
- Abstract
- Although perylene bisimide (PBI) has excellent luminous efficiency and high thermal stability, terylene bisimide (TBI) has been developed because the emission wavelength is shorter for using as a red organic phosphor. However, although the emission wavelength of TBI is longer, the solubility in organic solvents is poor due to the stronger planar structure than PBI. In this research, we prepared TBI and PBI with swallow-tail group which is known to lead to great solubility. The structure and properties of TBI and PBI were analyzed by H-NMR, FT-IR, UV/Vis spectroscopy and thermogravimetric analysis (TGA). (3-9) showed excellent thermal stability with less than 5 wt% weight loss up to 415℃ in TGA analysis. In the solubility test, TBI exhibited good solubility of more than 5 wt% in chloroform. The maximum absorption wavelength of (3-9) in the UV/Vis spectrum were 647 nm, and the maximum emission wavelength were 676 nm. Synthesized TBI were mixed with PMMA (polymethyl methacrylate). Thin film showed peaks at 680 nm in the photoluminescence spectra. (3-9) was found to be a possibility as a red organic phosphor for hybrid LED.
