  Surface-Bound Porphyrazines:  Controlling Reduction Potentials of Self-Assembled Monolayers through Molecular Proximity/Orientation to a Metal Surface

  摘要：

  We report the preparation of two novel H-2[pz(A(n);B4-n)] porphyrazines (pzs) which were designed to position themselves quite differently when attached to a surface: one to form a standard self-assembled monolayer (SAM) roughly perpendicular to a surface, the other to lie horizontally along a surface. As the former, we synthesized a pz, 1, where one pyrrole group is functionalized with two thioethers terminated in mercaptides (SR, R = (CH2)(3)CONH(CH2)(2)S-), each protected as a disulfide, and -S-Me is attached to the other pyrrole sites; the latter is a pz, 2, with dialkoxybenzo groups fused to two trans-pyrroles of the pz ring, and SR groups are attached to the other pair of pyrroles. Nanostructures of 1 and 2 were successfully patterned on gold surfaces via dip-pen nanolithography, and the predicted molecular orientation of the resulting structures was confirmed by topographic AFM images. The two pzs exhibit similar reduction potentials in solution. Both show large shifts in potential upon surface binding, with the magnitude of the shift depending on the proximity/orientation of the pz to the surface. The first reduction potential of the "vertically" aligned 1 shifts by ca. +430 mV when incorporated in a binary pz/hexanethiol SAM, while that for 2, which lies flat, shifts by ca. +800 mV; the potential thus shifts by ca. +370 mV upon taking a given pz that stands atop a two-legged insulating "standoff" in a traditional SAM and "laying it down". We suggest these observed effects can be explained by image-charge energetics, and this is supported by a simple model.

  Synthesis of Near-IR Absorbing/Emitting Porphyrazine Derivatives with Tunable Solubility

  摘要：

  We report the synthesis of porphyrazines (pzs), or tetraazaporphyrins, of the form H(2)[pz(A(n;)B(4-n))], where A is [S(CH(2))(3)COOR](2) (R = n-Pr, H) and B is a fused beta,beta'-diisopropyloxybenzo group, including the compounds with n = 4 (6), n = 3 (7) and the trans compound with n = 2 (8) (Scheme 1). The synthesis employs Linstead crossover macrocyclization of dimethyl 6,7-dicyano-5,8-dithia-6(Z)dodecenedioate, MNT(C(4)O(2)Me)2 (2), with 1-imino-4,7-bis(1-methylethoxy)-1H-isoindole-3-amine (4). These pigments were characterized by (1)H NMR, 13C NMR, absorbance/fluorescence spectroscopy, mass spectrometry, and microanalysis. An X-ray crystal structure of 8 is presented. Of particular note, 6-8 display intense near-IR absorbance and dual UV-visible/near-IR emission which are very important in potential biomedical applications, both for cancer therapy (photodyanamic therapy, PDT) and cancer diagnosis (optical tumor imaging). For example, the trans-porphyrazine 8 has an intense long-wavelength absorption at ca. 800 nm (log epsilon = 4.18) and S1 fluorescence at similar to 820 nm, where mammalian tissue is effectively penetrated by light. Transformation of the ester group permits a wide range of functionality and solubility to be generated without change in optical properties. As an example, hydrolysis of these compounds by LiOH in THF/H(2)O gives the corresponding carboxylato-functionalized pigments 9-11, which are described. The last of these dissolves without aggregation in fetal calf serum.

  Porphyrazines (pzs), or tetraazaporphyrins, can be viewed as porphyrinic macrocycles in which the porphyrin meso (CH) groups are replaced by nitrogen atoms; as such, it can be anticipated that pzs would show similar biocompatibility and biodistribution to those of porphyrins. However, distinctive chemical and physical features of the pzs differentiate them from either the porphyrins or phthalocyanines, in particular making them excellent candidates as optical imaging/therapeutic agents. The novelty of the pzs requires that we first determine how specific structures selectively alter biological function, leading to the development of "rules" that will be used to predict future biologically functional pzs. In the first of these studies, we present here a correlation of pz charge with biocompatibility for a suite of three pzs-neutral, negative, and positive. Confocal fluorescence microscopy and proliferation/viability measurements disclose that the three pzs differ in their toxicity, uptake, and localization. in A549 human lung adenocarcinoma cells and WI-38 VA13 normal cells. Interestingly, the negatively charged pz exhibits selective dark toxicity in pulmonary adenocarcinoma cells.
