Multiple Azoarenes Based Systems - Photoswitching, Supramolecular Chemistry and Application Prospects

In the recent decades, the investigations on photoresponsive molecular systems with multiple azoarenes are quite popular in diverse perspectives ranging from fundamental understanding of multiple photoswitches, supramolecular chemistry, and various application prospects. In fact, several insightful and conceptual designs of such systems were investigated with architectural distinctions. In particular, the demonstration of applications such as data storage with the help of multistate or orthogonal photoswitches, light modulation of catalysis via cooperative switching, sensors using supramolecular host-guest interactions, and materials such as liquid crystals, grating, actuators, etc. are some of the milestones in this area. Herein, we cover the recent advancements in the research areas of multiazoarenes containing systems that have been classified into Type-1 {linear, non-linear, and core-based (A)}, Type-2 {tripodal C₃ -symmetric (C3)} and Type-3 {macrocyclic (M)} structural motifs.

GiPlot: An interactive cloud-based tool for visualizing and interpreting large spectral data sets

Latest advances in technology and the growing amount of experimental and business data have increased the number of users accessing on-line tools dedicated to quickly visualize and analyse large data sets. This paper describes the development and functionality of a new interactive cloud computing based plotting tool (GiPlot - Google-based Interactive Plot) easy-to-use for universal data. It has interactive features that facilitate data share and interpretation, and selection of specific data suitable for further uses and detailed studies. It also allows quick and step-by-step visualizations of the impact of various experimental conditions on spectral data sets. For a detailed illustration of the features of this interactive plotting tool, we have used mainly spectral data for a given solute dissolved in mixed solvents and for changes in the absorption and/or fluorescence properties of a solute solution in the presence of different chemical stimuli. The most important features and functionalities of this new tool have also been summarized and suggestively highlighted through a short collection of video tutorials containing many examples, developed by the authors of this paper as a support for both the tool and this paper.
