Photo- and Electrical Features of Semisynthetic Macrocyclic Compounds such as porphyrins, pheophorbides, chlorins, etc. are reviewed. It was shown for the first time that the macrocyclic compound Cu-MCC in a mixture with a polymer (poly(N,N′-bis-4-butylphenyl-N,N′-bisphenyl)benzidine, poly-N-vinylcarbazole) can (1) expand the photoconductivity of the composite in the blue and red spectral bands, (2) serve as an electron acceptor in relation to the polymer in the same way as fullerene, (3) provide transport both electrons and holes, (4) serve as light emitting dopant demonstrating electroluminescence in the near-IR range. The corresponding mechanisms of hopping transport of charge carriers, photoconductivity and electroluminescence in the studied composites, as well as the operating parameters of the developed devices are discussed.
