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

  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.
• Varying the Electrochemical Potential and Thickness of Porphyrazine SAMs by Molecular Design

  A series of multithiol-functionalized free-base and Zn-coordinated porphyrazines (pz's) have been prepared and characterized as self-assembled monolayers (SAMs) on Au. The synthetic flexibility of the pz's provides a unique opportunity to tune their electronic and chemical characteristics and to control the distance of the redox-active pz macrocycle from the Au surface. This allows us to study the reduction potentials of these surface-bound pz's as a function of film thickness and molecular charge distribution using angle-resolved X-ray photoelectron spectroscopy and cyclic voltammetry. Upon SAM formation, the reduction potentials of all pz's show a significant positive shift from their formal potentials when free in solution (up to similar to +1 V), with the magnitude of the shift inversely related to the Au-pz distance as determined from the film thickness of the pz SAM (thicknesses ranging from 3.5 to 11.8 angstrom). When the pz lies down oil the surface, in a SAM of thickness -3.5 angstrom, the charge distribution within a pz macrocycle also plays a role in determining the potential shift. These observations are consistent with our originally proposed mechanism for potential shifts upon binding to a metal surface based on image charge effects and with the analysis of Liu and Newton (J. Phys. Chem. 1994, 98, 7162).
