containing one (1 and 3) or three pyrene (2 and 4) anchors, covalently linked to porphyrins (free base or Zn), were prepared and characterized. All of them enable their π-π stacking onto low-dimensional nanocarbons including single-walled carbon nanotubes (SWCNTs) and nanographene (NG), their individualization, and their characterization. Microscopic (TEM, AFM) and spectroscopic (steady state UV-Vis and
制备并表征了一系列分子前体,包含一个(1 和 3)或三个芘(2 和 4)锚,共价连接到卟啉(游离碱或 Zn)。所有这些都使它们的 π-π 堆积在低维纳米碳上,包括单壁碳纳米管 (SWCNT) 和纳米石墨烯 (NG),它们的个性化和表征。显微(TEM、AFM)和光谱(稳态 UV-Vis 和荧光、光谱电化学和瞬态吸收测量)技术处于表征的前沿,并辅以拉曼光谱。拉曼分析非常重要,由于在固态探测时与 1-4 的相互作用,拉曼分析证实了纳米碳的 n 掺杂。然而,在解决方案中,情况完全不同。
