Special Issue Information

Dear Colleagues,

Dyes are widely used in the textile, pharmaceutical, food, cosmetics, plastics, paint, ink, photographic and paper industries. Moreover, the traditional dyes have been developed into functional dyes, which can be further used in semiconductors, photosensitizers, emitters in optoelectronics devices, optical and luminescent sensors for biological and environmental monitoring systems, and therapeutic agents for medical purposes, and so on.

Dye’s characteristics are closely related to their photochemical properties, which has been investigated thoroughly. For example, dyes with photon absorption/emission at distinct wavelengths can be used as the industrial colorants or potential optical signal indicators in chemosensors; dyes with white-light emission are used in solid-state lighting, flat-panel display devices, and backlights for liquid crystalline display; dyes with the ability to produce singlet oxygen under light irradiation can be used for photodynamic therapy (PDT); dyes are used as the photosensitizers in dye-sensitized solar cells (DSSCs) for their abilities of photoexcitation and electron injection. On the other hand, dye properties are further optimized through the modification of molecular structures, which is promoted by the organic synthesis.

This Special Issue entitled “Study on Synthesis and Photochemistry of Dyes” welcomes manuscripts (original research papers, short communications, or focus reviews) pointed out by the keywords given below. However, other related topics are also welcome.

Hydrogen-bonded organic frameworks (HOFs) are a kind of crystalline porous material that have shown great potential for photocatalysis on account of their mild synthesis conditions and high crystallinity. Perylene-based photocatalysts have great potential for photocatalytic H2O2 production due to their excellent photochemical stability and broad spectral absorption. In this work, we designed and synthesized a high crystalline perylene-based HOF (PTBA) and an amorphous analog sample PTPA for photocatalytic H2O2 evolution. Under visible light irradiation, PTBA shows a higher photocatalytic H2O2 production rate of 2699 μmol g−1 h−1 than PTPA (2176 μmol g−1 h−1) and an apparent quantum yield (AQY) of 2.96% at 500 nm. The enhanced photocatalytic performance of PTBA is attributed to the promotion of the separation and transfer of photocarriers due to its high crystallinity. This work provides a precedent for the application of HOFs in the field of photocatalytic H2O2 generation. Full article
