The magnetic moment of an electron is (semiclassically) modeled by a loop of current threaded by a flux quantum +o=?ry The integral of the charge density involved in the current is taken to equal the electronic charge. It is shown that the assumption that the moment’s flux is quantized to a value Go implies that the size of the @are) electronic charge must be extremely small (< 10-57 cm) but the most appropriate loop radius is on the order of the electron Compton radius XeO Using these results, a classical calculation of the static electric and magnetic energies associated with the loop is shown to be in reasonable agreement with the physically observed electron mass o (Submitted to Am.

plot of the one-electron oxidation potentials versus N21 exhibits good linearity. The inter-cept (20.38 V) of the plot may be assigned for the one-electron oxidation potential of the “infinite ” fused porphyrin polymer. In spite of their remarkable properties, in-cluding extremely low HOMO-LUMO (highest occupied/lowest unoccupied molecular orbital) gaps, low one-electron oxidation potentials, and rigid and giant molecular size, the triply linked arrays are stable in air and easily manipulated, and should prove useful for studies on the vi-bronic coupling of organic molecules. They may also find use as conducting molecular wires and in molecular-scale electronic devices. In addition, the unusual photophysical and elec-trochemical properties of these fused porphyrin arrays suggest potential avenues for further in-vestigation, including the development of near-IR and IR sensors and dyes, and materials for nonlinear optics and spin ordering.
