چکیده

An air-stable photoresponsive viologen molecular system is constructed based on a three-fold accordion interpenetrating packing arrangement. The fluorescent modulation process is coupled with a photochromic reaction via energy and electron transfer between the adjacent donor and acceptor groups.

Novel Schiff Bases of Pyrrole: Synthesis, Experimental and Theoretical Characterizations, Fluorescent Properties and Molecular Docking

Some new Schiff-base compounds based on pyrrole were synthesized by the reaction of 2-amino-1-methyl-4,5-diphenyl-1H-pyrrole-3-carbonitrile (1)with aromatic aldehydes (2a-2e) in ethanol/acetic acid at room temperature. The structures of the Schiff bases were characterized by full spectral data. The fluorescence emission intensity of the Schiff bases has bee...

Nonlinear solid-state filter based on photochromism induced by 2-photon absorption in a dye-doped sol-gel

There is much interest in enhancement of the absorbance performance of nonlinear absorber solid-state filters. In this work we present an advanced reversible nonlinear filter based on a dye-doped sol-gel matrix. The absorbance enhancement was achieved by using a combination of two absorption mechanisms in the same molecule; a photochromic absorption which is induced by 2-photon absorption (2PA)...

Design of Viologen-Based Liquid Crystals Exhibiting Bicontinuous Cubic Phases and Their Redox-Active Behavior

We have succeeded in developing viologen-based liquid-crystalline materials forming bicontinuous cubic phases. They are composed of amphiphilic zwitterions with a viologen ionic-head-group and sulfonyl-imide-type acids. In the bicontinuous cubic liquid-crystalline assemblies, the ionic-head groups of the amphiphiles align along a gyroid minimal surface, forming a 3D continuous viologen layer. T...

A Photochromic Sensor Microchip for High-performance Multiplex Metal Ions Detection

Current multi-analytes chips are limited with requiring numbers of sensors, complex synthesis and compounds screen. It is expected to develop new principles and techniques to achieve high-performance multi-analytes testing with facile sensors. Here, we investigated the correlative multi-states properties of a photochromic sensor (spirooxazine), which is capable of a selective and cross-reactive...

A photochromic and thermochromic fluorescent protein

Photochromism is a change of colour induced by irradiation with light, while thermochromism is a change of colour due to a change of temperature. Both photochromism and thermochromism have been observed in inorganic and organic compounds, however thermochromism is much less common in biological systems. One mechanism by which molecular photochromism can occur is a photo-induced isomerization to...
