“…The proton ( 1 H) NMR spectrum of the ZnPc NW further proves that the ZnPc NW contains pure ZnPc without any structural change (Supplementary Figure S5). 29 The as-grown ZnPc NW disperses well in water with mechanical agitation by sonication (Figure 2a top row). The degree of dispersion of ZnPc NW in water gradually increases as a function of sonication time, which is easily noticed by the color change of the solution from transparent pale blue to dark blue.…”

Significant increase in the water dispersibility of zinc phthalocyanine nanowires and applications in cancer phototherapy

The phototherapy is one of the widely accepted noninvasive clinical methodologies to eradicate cancer cells owing to its minimal side effects and high selectivity to the light of specific wavelength. As represented by photodynamic (PD) and photothermal (PT) therapy, the phototherapy requires light and photosensitizer to generate reactive oxygen species and heat, respectively. Zinc phthalocyanine (ZnPc) is one of the promising photosensitizers as it has a strong absorption cross-section in the spectral range of 650-900 nm that guarantees maximum tissue penetration. One critical issue in using Pc molecule, including ZnPc as a biocompatible sensitizer is the poor water solubility. To increase water solubility, various chemical modifications inducing hydrophilicity have been widely attempted to introduce various functional groups in the ZnPc backbone. We report that ZnPc nanowires (NWs) directly grown from ZnPc powder by vaporization-condensation-recrystallization process show surprisingly increased water dispersibility without any functionalization. The ZnPc NW solution exhibits highly efficient dual PD and PT effects upon the irradiation of near infrared (808 nm) laser. The dual phototherapeutic effect of ZnPc NW is proven to enhance cytotoxic efficiency according to both in vitro and in vivo experimental results.

PDT selectively destroys neoplastic lesions using cytotoxic reactive oxygen species (ROS) generated by light activation of the photosensitizer. 1,2 One of the crucial factors determining the PDT efficacy is the photochemical and photophysical properties of the photosensitizer. 3,4 Currently, four main classes of photosensitizer, such as porphyrin derivatives, chlorins, porphycenes, and phthalocyanines (Pcs), have been approved by the U.S. Food and Drug Administration (FDA) for clinical applications against cancer. 5,6 Among these, metallo-phthalocyanine has attracted considerable interest, having a photodynamic (PD) property that can be readily tuned by the type of central metal ion and the functional groups introduced as a Pc ring substituent. Zinc phthalocyanine (ZnPc) is known to exhibit a high PD effect as it possesses a diamagnetic Zn(II) central metal ion whose d shell is fully occupied, by which the yield of triplet excited state with long lifetime essential for the generation of ROS becomes high. 7 Moreover, ZnPc has

“…More importantly, the ability to control size and shape provides enhanced optoelectronic properties due to size- and shape-dependent effects and collective behaviors from the assembled building blocks [ 21 , 22 ]. So far, numerous inorganic- and organic-based nanostructures have emerged as new building blocks to construct photocatalysis systems [ 23 , 24 , 25 , 26 ]. However, compared to inorganic nanostructures, the organic counterparts have received special attention attributed to their considerable flexibility in molecular design, excellent tunability of the optoelectronic properties and their nice solution processability [ 17 , 27 , 28 , 29 , 30 ].…”

Well-defined organic nanostructures with controllable size and morphology are increasingly exploited in optoelectronic devices. As promising building blocks, porphyrins have demonstrated great potentials in visible-light photocatalytic applications, because of their electrical, optical and catalytic properties. From this perspective, we have summarized the recent significant advances on the design and photocatalytic applications of porphyrin-based nanostructures. The rational strategies, such as texture or crystal modification and interfacial heterostructuring, are described. The applications of the porphyrin-based nanostructures in photocatalytic pollutant degradation and hydrogen evolution are presented. Finally, the ongoing challenges and opportunities for the future development of porphyrin nanostructures in high-quality nanodevices are also proposed.
