“…Indeed, due to low-energy electronic states, phthalocyanines and naphthalocyanines, particularly multipledecker compounds, are less well suited for sensitizing NIRemitting lanthanide ions. The field has been reviewed regularly since the turn of the century, 32,256,260,[270][271][272][273][274] including applications to bioanalysis and bioimaging. [275][276][277][278] In some instances, polyaminocarboxylic acid groups 115,279 or tris(dipicolinates) 213 have been attached to porphyrins or to their transition metal complexes (M = Zn, Pd, Pt); the flexibility of the resulting assemblies is large enough to bring the Ln III ions close to the porphyrin core which then can sensitize their luminescence.…”

“…As a result, the energy of excited singlet or triplet state for Gd-porphyrin can transfer to the ground state, along with the strong fluorescence emission and 1 O 2 generation. As for Cu ions, since the orbital energy level of Cu 2+ (5015 cm −1 ) is lower than that of the triplet state of porphyrin (∼14,000 cm −1 ), 47,63,64 the energy of the excited state for porphyrin would directly transfer to Cu ions and be dissipated via nonradiative pathways, instead of transferring to the ground state of porphyrin. Thus, Cu ions in Gd/Cu-nanosheets could not only quench the fluorescence of Gd-porphyrin but also blocked 1 O 2 generation.…”

Colon cancer is the third most common malignancy and the fourth most prevalent cause of death worldwide. Unfortunately, current cancer treatment approaches suffer from low specificity toward colon cancers and lack of facile imaging method to monitor a real-time therapeutic process, usually resulting in severe toxicity to normal tissues. Thus, to achieve precise therapy for colon cancer, we developed a "one-key triple-lock" bis-metal ultrathin coordination network (Gd/Cu-nanosheets) as the first H 2 S-unlocked molecular dipoles with activatable fluorescence, magnetic resonance imaging (MRI), and photodynamic effect. Notably, within noncancerous tissues, Cu ions can lock up MRI signal, fluorescent emission, and 1 O 2 generation of molecular dipoles (Gd-porphyrins). Under the trigger of endogenous H 2 S overexpressed colon cancer model (HCT116), the loss photodynamic effect of the as-disassembled Gd-porphyrin was recovered for efficient and potent killing of colon cancer cells in vivo, with minimization of toxic side effect toward normal tissue. By combining the complementary advantages of bimodal MRI/ fluorescence imaging, Gd/Cu-nanosheets enabled high-specificity visualization of colon cancer in living cells and in vivo upon activation of H 2 S. Moreover, a good correlation between the fluorescence intensity of Gd/Cu-nanosheets and cancer inhibition rates afforded the ability to self-report cancer therapeutic outcomes, thereby providing a potentially powerful tool for personalized and precise treatment of colon cancer.

“…[16,17] We also have studied mononuclear complexes formed by Er(III) with ditopic porphyrins and corroles bearing peripheral binding sites as convenient building blocks which can be used to form polynuclear tetrapyrrole-based complexes. [18][19][20] These ditopic porphyrins and corroles were synthesized through the acylation of parental aminoderivatives (H The erbium complexes with these functionalized porphyrins and corroles were formed with ratio Er:L = 1:1, erbium ions were located in peripheral binding centers.…”

The luminescent properties of the series of erbium(III) complexes of various coordination types with different tetrapyrrole macrocycles (porphyrins, phthalocyanines and corroles) are discussed in this paper. The investigated series of compounds include mononuclear porphyrinato complexes (metal-ligand ratio 1:1, tppEr(acac)), sandwich phthalocyaninato-porphyrinato type complexes (metal-ligand ratio 1:2 [(15C5) 4 Pc]Er[(4-BrC 6 H 4) 4 Por] or 2:3-(Pc) Er[(15C5) 4 Pc]Er(Pc) and [(15C5) 4 Pc]Er[(15C5) 4 Pc]Er(Pc)), ditopic porphyrins and corroles possessing peripheral lanthanides binding (metal-ligand ratio 1:1, Er-edta-H 2 atpp•2H 2 O, Er-Hdtpa-H 2 atpp, Er-edta-H 3 dpfc•2H 2 O and Er-Hdtpa-H 3 dpfc). 4f-Luminescence in the near-infrared region is observed in all studied Er-complexes as a result of intramolecular transfer of excitation energy. The unique features of each type of complexes are discussed in details. The peripheral complexes are dual-emissive: they display both erbium(III) 4f-emission in near-infrared and molecular fluorescence in the visible spectral region. The values of quantum yield of molecular fluorescence as well as the intensity of 4f-luminescence are estimated. It was found that the binding type of erbium(III) plays a key role in the macrocycle excited state relaxation. The doubledecker heteroleptic complex [(15C5) 4 Pc]Er[(4-BrPh) 4 Por] possesses unusual emission behaviour.
