有機半導体共結晶の合成・構造および光物性

我们研制了一种新的激发态分子内质子转移活性化合物DSBTBT。从单晶结构测量来看，DSBTBT单晶呈现出一层一层的人字形叠加基序，层内π-π重叠出现滑移。我们研究了DSBTBT化合物的光学性质。DSBTBT晶体在稀释溶液中发射极弱，而在固态中发射增强。另一方面，DSBTBT单晶表现出光波导边缘发射特性。在脉冲激光激发下，以DSBTBT单晶为增益介质，观察到自发辐射的放大。

We developed a novel excited state intramoecular proton transfer (ESIPT)-active compound DSBTBT. From the single crystal structure measurement, DSBTBT single crystal shows layer by layer herringbone stacking motif with slipped intralayer π-π overlap. We studied the optical properties of the DSBTBT compound.DSBTBT crystal shows the very weak emission in the diluted solution but enhanced emission in the solid state. On the other hand, DSBTBT single crystal shows the optical waveguide edge emission property. Upon the pulsed laser excitation, the amplified spontaneous emission is observed based on the DSBTBT single crystal as the gain media.
