Multichannel selective, anisotropic, or consistent polarized-photon out-coupling has been realized in a set of 2Dorganicmicrocrystals, with the polarization direction and degree being either varied or retained with respect to the source luminescence. The molecular arrangement and spatial distribution of the transition dipole moments are found to play prominent roles in determining the polarization
prepare organic microspheres and crystalline microrods with circularly polarized luminescence (CPL) properties. The in situ protonation and co-assembly of a series of pyridine-functionalized chromophores and a chiral binaphthol phosphoric acid give rise to blue-to-yellow emissive amorphous microspheres and green- and yellow-emissive crystalline microrods with good fluorescence quantum yields (9.6–64.6%)
定义明确的发光微/纳米结构是微型光子器件的重要组成部分。在这项工作中,采用一种简单的方法制备具有圆偏振发光 (CPL) 特性的有机微球和结晶微棒。一系列吡啶功能化发色团和手性联萘酚磷酸的原位质子化和共组装产生蓝-黄发射无定形微球和绿-黄发射结晶微棒,具有良好的荧光量子产率(9.6– 64.6%)。微棒 (∼10 -3 )的发光不对称因子 ( g lum )) 被发现比微球大一个数量级。这些微观结构和相关材料通过荧光显微镜、扫描电子显微镜、单晶和粉末 X 射线衍射以及傅里叶变换红外光谱分析进一步表征。这些微结构明确的形态和有前途的发光特性使它们有可能用于手性光子应用。
