Abstract

Abstract : The cover picture shows that single‐molecular conductance ( G ) of heterogeneous oligomers can be analyzed in terms of the partial transmission probabilities ( T i ) of the component units of the oligomer, using a simple equation G = G 0 ∏ i N T i . This is a logical extension of the concept of a decay constant β for single‐molecular conductance of homogeneous oligomers, and is very useful if the limitation is recognized. Since T i contains the transfer integrals between different sites, they depend on how each unit is connected. Despite the limitation, the relation stands very nicely in a series of heterogeneous porphyrin arrays. More information can be found in the Communication by Ogawa et al. (DOI:10.1002/slct.201701015 ).
