Development of next-generation organic light-emitting devices using novel proton-transfer laser dyes

为了实现下一代有机发光器件，如有机半导体激光器，我们将重点放在表现出激发态分子内质子转移(ESIPT)反应的质子转移激光染料上，因为它们有利于在没有浓度猝灭的情况下产生高增益介质。在这项研究中，我们成功地开发了一种显示ESIPT的锌配合物，从中观察到了放大的自发辐射。

Toward realization of next-generation organic light-emitting devices such as organic semiconductor lasers, we focused on proton-transfer laser dyes showing an excited-state intramolecular proton transfer (ESIPT) reaction since they are advantageous for creating a high-gain medium without concentration quenching. In this study, we successfully developed a zinc complex showing ESIPT, from which amplified spontaneous emission was observed.
