Convergent synthesis of multiporphyrin light-harvesting rods

摘要

The present invention provides a convergent method for the synthesis of light harvesting rods. The rods are oligomers of the formula A1(Ab+1)b, wherein b is at least 1, A1 through Ab+1 are covalently coupled rod segments, and each rod segment A1 through A1+b comprises a compound of the formula X1(Xm+1)m wherein m is at least 1 and X1 through Xm+1 are covalently coupled porphyrinic macrocycles. Light harvesting arrays and solar cells containing such light harvesting rods are also described, along with intermediates useful in such methods and rods produced by such methods.
