The cover illustrates reversible binding of ligands (oxygen and nitrogen bases) to metalloporphyrin receptors at the solution/solid interface. This exchange can be followed with STM imaging as a function of time to determine if the process reaches equilibrium. The solution/solid interface provides a dynamic environment where reaction rates can be controlled by varying solution pH, temperature and reactant concentration. With single molecule microscopy it is possible to acquire both qualitative and quantitative information about molecule binding affinity, reaction equilibrium kinetics and thermodynamics.

pp. 993–1002Single molecule level studies of reversible ligand binding to metal porphyrins at the solution/solid interfaceUrsula Mazur* and K. W. Hipps*
STM can effectively probe single porphyrin receptor–ligand binding events at the solution/solid interface and provide both qualitative and quantitative information about molecule binding affinity, reaction kinetics and thermodynamics.
pp. 1003–1012Screening metal-dicorrole-based dyes with excellent photoelectronic properties for dye-sensitized solar cells by density functional calculationsLifeng Zheng, Yang Meng, Xiangqian Wang, Chun Zhu* and Jin-Xia Liang*
Different architectures of metal dicorroles were designed by varying the linking forms and the most stable architecture a was screened out by binding energy calculations with density functional theory. Based on the most stable architecture, a GaSN dye with excellent photoelectronic property was constructed for dyesensitized solar cells.

pp. 1013–1020Development of alkyne-BODIPYs as viscosity sensitive fluorescent probes for enumeration of bacterial cellsDijo Prasannan, Suchithra Tharamel Vasu, Chellaiah Arunkumar and Pattiyil Parameswaran*
The planar and twisted conformation within a BODIPY molecular structure decides its viscositydependent behavior. As the variations in fluorescence lifetime and intensity could be attributed to the local viscosity, the dye has been successfully employed in the bacterial enumeration of microbes by considering the proportionate fluorescence intensity of the BODIPYs as an index of the number of cells per ml.
pp. 1030–1037Synthesis and properties of a photochromic perina-phthothioindigo conjugated with two porphyrinsKazuya Ogawa*, Masaki Sato and Kenta Terao
A new porphyrinperinaphthothioindigo composite, where two porphyrins are connected to a perinaphthothioindigo dye though a triple bond, was synthesized. Reversible photoisomerization between the trans- and the cis-isomers was successfully carried out.
pp. 1021–1029Diameter-dependent structural and electronic property of fused porphyrin nanotubes: A density functional studySomnath Chowdhury, Monoj Das, Prajna Mukherjee and Bikash C. Gupta*
A density functional theorybased systematic study has been carried out on fused porphyrin based nanotubes. The stability of the nanotubes increases with increasing diameter. The transition metal atom plays a pivotal role in determining the stability as well as the electrical properties of the nanotubes (ScPNTs and TiPNTs). TiPNTs are more likely to be formed over ScPNTs. It is also observed that the ScPNTs are metallic in nature and the TiPNTs are semiconductors with small band gap.
pp. 1038–1046Hyperbranched lutecium phthalocyanines grafted ethylenediamine@graphene oxide with enhanced nonlinear optical propertiesZengduo Cui, Xin Wang, Jiale Ding, Yunhe Zhang, Zhenhua Jiang and Xuefeng Li*
In order to improve the dispersibility of graphene oxide (GO) in organic solvents and polymer matrixes, lutecium phthalocyanine (LuPc) and hyperbranched lutecium phthalocyanine (HBLuPc) were grafted on the surface of GO, respectively. It was found that the electron transfer between phthalocyanine and GO was promoted after surface modification. At the same time, due to the synergistic effects of nonlinear mechanisms such as nonlinear scattering (NLC), twophoton absorption, reverse saturable absorption (RSA), and photoinduced electron or energy transfer (PET/ET) from electron donor (phthalocyanine) to acceptor (GO), the hybrid has stronger NLO properties than GO and phthalocyanines.

pp. 1047–1053Synthesis, in vitro inhibition effect of novel phthalo-cyanine complexes as carbonic anhydrase and paraox-onase enzyme inhibitorsEmre Güzel, Barış Seçkin Arslan, Kübra Çıkrıkçı, Adem Ergün, Nahit Gençer,Oktay Arslan, İlkay Şişman and Mehmet Nebioğlu*
The preparation and assessment of enzyme inhibition properties of 3(2(5 amino4(4bromophenyl)3methyl1Hpyrazol1yl)ethoxy)phthalonitrile and its nitrogencontaining nonperipheral phthalocyanine derivatives were reported for the first time. The synthesized compounds were tested for their inhibitory activity against paraoxonase enzyme (PON1) and carbonic anhydrase isozymes hCA I and II.
pp. 1054–1065Synthesis, photoinduced amination and topological indices of novel porphyrin dyadsMuhammad Yaseen*, Muhammad A. Rashid, Muhammad A. Iqbal, Zahid Farooq, Muhammad Idrees, Muhammad A. Qayyum, Azeem Intisar, Mian HR. Mahmood, Ibrahim Khan and Muhammad Latif
This work refers to a nickelcatalyzed photoinduced amination study of βbromotetraarylporphyrin and its Ni(II), Zn(II) and Cu(II) complexes with three different amines. Nickelcatalyzed amination yields are compared with traditional Buchwald–Hartwig amination yields. Due to the low operational cost, photoinduced nickelcatalyzed C–N couplings were found to be more economical than the Buchwald–Hartwig amination procedure, although the latter afforded higher yields.
pp. 1066–1073Rigid trisporphyrin with 1,3,5-triazine core: Synthesis, spectroscopy, and DABCO-induced self-assembly propertiesChunhua Huang*, Bin Shen, Kang Wang*, Jing’an Lu and Xiao’fei Sun
The zinc complex of 2,4,6tris(5,10,15triphenylporphyrinatozinc)1,3,5 triazine with three porphyrin moieties bridged by a rigid 1,3,5triazine group (1), was synthesized and characterized. UVvis spectrophotometric and 1H NMR spectro photometric titrations of compound 1 were performed to study the DABCOinduced self and disassembly processes.
pp. 1074–1082Fluorous phthalocyanines and subphthalocyaninesKosuke Yoshinaga, Leo Delage-Laurin and Timothy M. Swager*
Synthesis and photophysical properties of phthalocyanines and subphthalocyanines with over 50 weight/percent fluorine is reported. These molecules display Haggregation features in fluorous solvents but display typical spectroscopic features in organic solvents. The Faraday rotation properties of these molecules are also discussed.
