Vertical organic nanowire arrays of 1,5-diaminoanthraquinone (DAAQ) on solid substrates were prepared by a facile physical vapor transport method. The crystal structure and growth direction of the nanowires were determined with electron diffraction. The color and fluorescence of the DAAQ nanowires can be bleached and quenched by acid vapor and rapidly regenerated by base vapor, making them useful as optical sensor materials. The ease of oriented vertical growth makes them promising nanophotonic elements that may be directly integrated into photonic devices during growth.
在固体基底上，通过简便的物理气相传输法制备了 1,5-二氨基蒽醌（DAAQ）的垂直有机纳米线阵列。通过电子衍射确定了纳米线的晶体结构和生长方向。DAAQ 纳米线的颜色和荧光可以被酸蒸气漂白和猝灭，并可以通过碱蒸气迅速再生，因此它们可用作光学传感器材料。由于易于定向垂直生长，它们有望成为纳米光子元件，在生长过程中可直接集成到光子器件中。
