“…The encapsulation studies using UV-vis spectroscopy showed that C 60 have high affinity for this kind of host molecules and that a zinc porphyrin-to-fullerene charge-transfer interaction occurs [307]. Zinc porphyrin tweezers linked through a dithiophene [308] or a cyclopentene [309] moiety show also the ability to accommodate fullerenes. Several bisphorphyrins linked through alkyl chains showing different rigidity have been successfully used to host fullerenes.…”

“…41) and different fullerenes (C 60 and C 70 ) demonstrate ground state interactions and fluorescence quenching of the cyclopentene linked Zn(II)Por dimeric tweezers by the fullerenes. 243 Moreover, the value of the K ass implies that the Por tweezers may be used as selective hosts for different fullerenes in benzonitrile. In addition, transient absorption measurements attest the sequence of energy transfer from the singlet excited state of the Por to the fullerene and electron transfer to the fullerenes in benzonitrile with a rate constant of 10 9 s À1 .…”

The remarkable properties of both phthalocyanines and porphyrins as individual building blocks have motivated the synthesis and study of homo- and heterobinuclear conjugates as light-harvesting systems. These planar chromophores share important electronic features such as high molar absorption coefficients, rich redox chemistry and interesting photoinduced energy and/or electron transfer abilities. In addition, some of these properties can be tuned by the introduction of different peripheral substituents and metal centres. In this review, we present relevant synthetic strategies for the preparation of covalent and supramolecular, homo- and heterobinuclear systems based on phthalocyanine and porphyrin chromophores, leading to a variety of architectures. In such systems, the degree of electronic interaction between the components is highly dependent on the electronic features of the two macrocycles, their linkage, and the molecular topology of the ensemble. In addition, incorporation of electroactive units into these binuclear systems has been pursued, affording multicomponent, donor-acceptor conjugates. In-depth photophysical characterization of the ground- and excited-state features of many of these homo- and heterobinuclear phthalocyanine and/or porphyrin ensembles has also been presented. Particular attention has been paid to understand the fundamental dynamics of the energy transfer and charge separation processes of these systems. This review intends to offer a general overview of the preparation of this class of compounds and the study of their photophysical properties which clearly show their potentiality as model compounds of light-harvesting complexes.

“…26,62 Bhattacharya and coworkers reported the remarkable double Suzuki coupling of a chiral meso-boronate porphyrin with 1,2-dibromocyclopentene to form the chiral tweezer diporphyrin 93 in 45% yield. 113 The authors used this molecule as a receptor for studies of supramolecular fullerene complexes. Osuka's group reported a suite of novel diporphyrins, prepared by treatment of β-acetylNiTriAP with samarium iodide, leading to pinacol 94, which underwent pinacol-pinacolone rearrangement to the one-C bridged 95a.…”
