“…In summary, our work and that of other groups around the globe [100][101][102][103] have pioneered the reductive electron transfer reactivity of 1D SWCNTs despite their p-type nature-Scheme 3. Surprising to us were CR dynamics on the order of tens of picoseconds, which were, in fact, (much) faster than those found in most conjugates featuring 0D empty fullerene/EMFs.…”

In this contribution, seminal works in the area of photon‐ and charge‐management are highlighted with focus on covalent electron donor‐acceptor conjugates built around porphyrins (Ps), on one hand, and 0D, 1D, and 2D nanocarbons, on the other hand. Photons in these conjugates are managed by Ps, while 0D, 1D, and 2D nanocarbons serve as the active component, which enable managing charges. With a few leading examples, it can be explored much beyond the simple photon‐ and charge‐management characterization and emphasize photovoltaics and photocatalysis to convert and store energy. This contribution concludes by highlighting recent progress in mixing and matching the unique charge‐management features of nanocarbons in the design of multidimensional nanocarbons.

“…[21,22] In recent years, the combination of porphyrins and nanocarbons, that is, fullerenes, carbon nanotubes, and graphene, have been explored. [23][24][25][26][27][28][29] A better understanding of the basic photophysical processes is, however, imperative to optimize the design, synthesis, and use of novel energy-harvesting materials. In the present study, we focused on photoinduced charge-transfer between three different zinc porphyrins and SWCNTs.…”

Herein, the microscopic and spectroscopic characterization of a novel non‐covalent electron donor−acceptor system, in which three different metalloporphyrins (1, 2, and 3) play the dual role of light harvester and electron donor with SWCNTs as electron acceptor, is described. To this end, microscopy, that is, atomic force microscopy (AFM) and transmission electron microscopy (TEM) corroborate the formation of 1‐SWCNT, 2‐SWCNT, and 3‐SWCNT. Spectroscopy by means of Raman, fluorescence, and transient absorption spectroscopy confirmed efficient charge‐transfer interaction from photoexcited metalloporphyrins to SWCNTs in the ground and excited state of 1‐SWCNT, 2‐SWCNT, and 3‐SWCNT. The complementary use of spectroelectrochemical and transient absorption measurements substantiates the formation of one‐electron oxidized metalloporphyrins after photoexcitation. Multiwavelength global analysis provides insights into the charge‐separation and recombination processes in 1‐SWCNT, 2‐SWCNT, and 3‐SWCNT upon photoexcitation. Notably, both the charge‐separation and recombination dynamics are fastest in 2‐SWCNT. Importantly, the strongest interactions in the steady‐state experiments are associated with the fastest excited state decay in the time‐resolved measurements.

Quantum-chemical calculations of the association of metal free, cobalt, copper and zinc phthalocyanines (MPc) with carbon zigzag and armchair nanotubes (CNTs) with diameters in the range of 7-14 Å were carried out by the DFT method with the use of BH van der Waals density functional and DZP atomic basis set. It was shown that interaction energy between the phthalocyanine molecules and the CNTs, as a whole, increases with an increase of the diameter of carbon nanotubes.However, in the case of CNT(n,0) the energy reaches its maximal value at n = 16 or 17 depending on the central metal atom and phthalocyanine orientation on the carbon nanotubes surface. Up to diameter of 10.5 Å of the CNTs, stronger binding of the considered MPc macrocyclic molecules is observed with carbon armchair nanotubes. However, in the case of higher diameters the phthalocyanines are associated more strongly with the zigzag CNTs.
