A simple pyrene based receptor has been synthesised and shown to exist in the dimeric form in solution exhibiting an excimer band in the emission spectrum. The proposed dimeric form is supported by the DFT calculations. Further, the excimer fluorescence is bathochromically shifted with decreased emission intensity in the presence of Hg(2+) suggestive of the formation of an aggregated complex. The sensing event also worked on the solid support; thus attesting the potential of the sensor for practical application in contact mode.
一种基于芘的简单受体已被合成，并显示在溶液中以二聚体形式存在，在发射光谱中呈现准分子带。密度泛函理论计算支持了所提出的二聚体形式。此外，在Hg(2+)存在下，准分子荧光发生红移，发射强度降低，这表明形成了聚集复合物。传感事件在固体支持物上也起作用；因此证明了该传感器在接触模式下实际应用的潜力。
