Two pairs of analogous zinc(II) phthalocyanines and 2,3- naphthalocyanines with eight butylthio or 3,6-dioxa-1-decylthio substituents have been synthesized and shown to exhibit a substantial aggregation tendency in organic solvents. The visible spectra of the octakis(3,6-dioxa-1- decylthio) naphthalocyanine 7 have been recorded in THF with different concentrations and the data have been analyzed using a nonlinear least- squares fitting procedure giving ε(m) (777 nm), ε(d) (777 nm), and K(d) at 1.95 x 106 M-1 cm-1, 1.29 x 105 M-1 cm-1, and 2.72 x 105 M-1, respectively. Simulated visible spectra for the pure monomeric and dimeric 7 have also been obtained. By variable-concentration and variable-temperature visible spectroscopic studies, the heats of aggregation of all these in toluene have also been determined (-17.1 to -105.0 kJ mol-1). These values depend-largely on the additional interactions due to the substituents. (C) 2000 Elsevier Science Ltd.

A series of subphthalocyanines (SubPcs) bearing a carboxylic acid group either at the peripheral or axial position have been designed and synthesized to investigate the influence of the COOH group positions on the dye-sensitized solar cell (DSSC) performance. The DSSC devices based on SubPcs with axially substituted carboxylic acid groups showed low photovoltaic performance, whereas peripherally substituted one exhibited higher power conversion efficiency owing to improved injection from LUMO of SubPcs to the TiO2 conduction band.
Trapping fullerenes with jellyfish-like subphthalocyanines

Six electronically different concave-shaped subphthalocyanines (SubPcs) have been prepared for testing the structural factors governing fullerenes encapsulation. Thus, the supramolecular interaction of SubPcs with C 60 and C70 fuller
