Photophysical properties of metal-mediated assemblies of porphyrins

Exciton/Charge-Transfer Electronic Couplings in Organic Semiconductors

“…48 Meanwhile, Zn-porphyrin is commonly used in dyesensitized solar cells 49 and in porphyrin-fullerene solar cells. 50 Porphyrins have an absorption onset near 450 nm 51 and have an important role in photosynthetic systems. 52,53 a) b) Figure 7: Attachment/detachment density plots for Zn-porphyrin:PTCBI illustrating a) nonlocal CT-like and b) localized exciton-like TDDFT states.…”

Investigation of the photophysical and eletrochemical properties of a free base tetrapyridyl porphyrin with meso carbon linked ruthenium(II) groups

“…On the other hand, ruthenium complexes have been extensively employed as sensitizer for DSSC during decades. Advances in molecular engineering have enabled the potential for ruthenium complexes to form supramolecular structures through attachment to the porphyrin ring [19,29]. This has been shown to substantially impact on the observed photophysical properties of both classes of molecules [29][30][31].…”

Two three-dimensional supramolecular networks built from metallophenols through hydrogen bonds and coordinate bonds

“…The resultant crystalline materials have potential applications in a range of fields, including optical, electronic, magnetic, absorbent, catalytic materials and so on [1][2][3][4][5][6][7][8][9]. Infinite 1-D, 2-D and 3-D nets built from organic and metal-organic components via hydrogen bonding and metal-to-ligand coordinate bonding have diverse topology, connectivity and interpenetration modes [10][11][12][13][14][15][16][17][18][19][20][21].…”
