| 제목 | Synthesis and Optical Properties of D-π-D Structured red emission DPP dyes containing Triphenylamine donors |
| 초록 | Diketopyrrolopyrrole(DPP)dyes are promising organic colorants with characteristics of intense color, excellent stabilities. Especially, red emitting DPPs have been adopted for numerous industrial applications such as photoconversion film and OLED. High quantum yield(Q.E), large stoke shift and high stabilities are vital properties in such industrial applications. In this study, three kinds of Donor-π-bridge-Donor(D-π–D) structured DPP red emitting dyes were synthesized. Synthesized dyes contained electron enrichment triphenylamine(TPA) moieties with/without adittional electron donating donors. Since the triphenylamines can induce steric hindrance to the entire dye structure, their aggregation can be disturbed. Therefore, higher quantum yield and bathochromic shift can be achieved The three synthesized dyes containing TPA moieties showed bathochromic shift and large stoke shifts compared to the dyes without TPA moieties. Although, their thermal stability and Q.E were not improved. |
