A novel bis(ferrocenyl chalcone) silicon(IV) phthalocyanine has been prepared in which the disulfide linker can be cleaved by dithiothreitol. The separation of the ferrocenyl quencher and the phthalocyanine core greatly enhances the fluorescence emission, singlet oxygen production and in vitro photocytotoxicity.

Four optically active {(2,3,9,10,16,17,23,24-octa[(S)-2-methylbutoxy]} phthalocyanine derivatives with different central metal ions, namely (S)-H2Pc(β-OC5H11)8 (1), (S)-ZnPc(β-OC5H11)8 (2), (S)-CuPc(β-OC5H11)8 (3), and (S)-NiPc(β-OC5H11)8 (4) have been synthesized and their self-assembly behaviors systematically investigated by electronic absorption and circular dichroism (CD) spectroscopy, sca...

Molecular catalysis for photocatalytic CO2 reduction (PCR) has recently attracted much attention, whereas its scaled practical application is usually limited by the difficulty of recycling and photochemical instability in homogeneous solutions. Immobilization molecular catalysts on solid matrices, that is, covalent bonds or noncovalent interactions, provides a great blueprint to tackle this iss...

Phthalocyanine covalent organic frameworks with different central metals are synthesized, and the AA-stacking structure of the 2D polymer sheets results in periodic phthalocyanine π-columns. The central metals control the π-electronic functions, including the improvement of light absorbance, the ease of carrier transport, and the photocurrent gain.

Several kinds of copper phthalocyanine-based conjugated microporous polymers have been synthesized, which present enhanced long-wavelength photon absorption capability and high efficiency for singlet oxygen generation under low energy light irradiation. This strategy opens a facile avenue towards expanding the scope of phthalocyanine-based porous materials with various internal structures and f...

The synthesis of metal nanoparticles (NPs) under controlled conditions in water remains a challenge in nanochemistry. Two different approaches to obtain platinum NPs, which involve the treatment of aqueous solutions of preformed sulfonated (NHC)Pt(ii) dimethyl complexes with carbon monoxide, and of (NHC)Pt(0) diolefin complexes with dihydrogen (NHC = N-heterocyclic carbene), are disclosed here....
