Special Issue Information

Dear Colleagues,

The last couple of decades have seen an increasing amount of R&D on molecules that undergo potentially useful phenomena under the effect of light, namely: the rotation of certain functional groups, ring opening/ring closure processes, release of protons, electrons, ions, and so on. Particularly special attention has been payed to the control and reversibility of these phenomena, so that their reactions could be reversed upon either cutting the light excitation or using a different wavelength. In this way, such molecules might be used as devices for the chemical control of certain processes under the external stimulus of light. This field of research, the same as many others in photochemistry, was foreseen by the genius of Ciamician as early as more than a century ago (“The photochemistry of the future”, G. Ciamician, Science 1912, 36 (926), 385–394, DOI: 10.1126/science.36.926.385). The field has reached what is, no doubt, one of its heights, with the award of the Nobel Prize in Chemistry in 2016 ( Finally, photochemically-driven processes are already one of the bases of a full branch of nanotechnology.

In view of all of the above-described, this Special Issue aims to compile a set of papers that cover the wide spectrum of light-driven processes are nowadays being studied, in order to reflect the incredible variety of applications in which they may be involved, and to serve as inspiration for other applications that we cannot even imagine right now.

All scientists in the field are cordially encouraged to submit their manuscripts for consideration for publication in this Special Issue.

Title: Silver nanoplates/polymer composites for flexible, high-thermal stability, spectral-tunable optical filtering

Abstract: Optical filtering is an important optical component that can eliminate light of unwanted wavelength and get the desired signal, which is widely used in imaging, detection and optical modulation fields. With the rise of intelligent and digital technology, the demand for flexible, high temperature resistance spectral-tunable
optical filtering is rapidly increased. In addition to spectral-tunable from visible to near-infrared, a major limitation for conventional optical filter with glass substrate is short of stretchable, high thermal stability and affordable price. In order to solve this problem, we doped silver nanoplates in polymers and characterized its transmission and reflection spectra from visible to near-infrared by controlling the size, distribution density and layer number of nanoplates. In addition, in contrast to the conventional composites whose nanoplates are unwrapped, we wrapped the nanoplates with silica and placed them in same polymers testing its mechanical and optical properties at different temperatures. It is found that the new films have excellent flexibility, thermal stability, oxidation resistance and spectra-tunable from visible to infrared. Furthermore, we have reasonably explained the reasons and carried out relevant mechanism studies.
