Colorimetric anion sensing by porphyrin-based anion receptors
Lee, Chanhyo,Lee, Dong Hoon,Hong, Jong-In
, p. 8665 - 8668 (2001)
Porphyrin derivatives 1-4 with H-bond donors and/or color-reporting chromophoric unit were synthesized and studied as anion-binding receptors. 1 and 2 exhibited binding selectivity in the order of AcO->H2PO4-?Cl-, Br-, I- in DMSO-d6. Color change tests with several different anions for colorimetric anion sensors (3 and 4) resulted in selectivities for F-, AcO- and H2PO4- in organic solution. While 1 and 2 exhibited good selectivities for AcO- and H2PO4-, 3 and 4 showed a dramatic color change for F- due to increased interaction with a nitrophenylazo phenolic OH group.

The controlled formation of complex and functional 1-, 2-, and 3D hierarchical assemblies from molecular building blocks represents a key current challenge. Herein, we report the use of a seeded growth approach for a series of perylenediimide-based molecules (PDIs 1–4) to access otherwise inaccessible self-assembly pathways that yield complex hierarchical structures. The key to the new approach is to use hetero-seeds which possess a different composition and morphology from that of the molecular building block. For example, a nanotube seed (from PDI 3) and a microribbon seed (from PDI 4) were found to initiate different self-assembly pathways for PDI 1, which normally assembles to yield nanocoils. This led to the formation of unprecedented 3D scroll-like and scarf-like hierarchical nanostructures, respectively. Also, the hetero-seeds from PDI 3 initiate hidden self-assembly pathways of PDI 2 to generate 1D tubular heterojunctions. Significantly, this new strategy offers new opportunities to create emergent and functional hierarchical and complex structures from small molecule precursors.
