Writing and erasing multicolored information in diarylethene-based supramolecular gels

Abstract

Diarylethene photoswitches in supramolecular gels constitute a system where the writing and erasing of multicolored fluorescent information is easily achieved.

Multi-color emission with orthogonal input triggers from a diarylethene pyrene-OTHO organogelator cocktail

“…Recently we reported supramolecular systems based on micelles 16 and LMWGs, 17 in combination with mixed fluorophore systems (referred to as ''cocktails'') that were capable of multi-color emission via all-photonic modulation. Such systems involve strategic utilization of energy transfer between chromophores in cocktails consisting of DAEs and fluorescent donor molecules.…”

Optical microresonator arrays of fluorescence-switchable diarylethenes with unreplicable spectral fingerprints

“…Diarylethenes 1, 2, and 3 were synthesized according to a reported procedure. 19,29,30 Photoabsorption spectra were recorded on a JASCO V-630 spectrophotometer. Steady-state PL spectra were measured on a JASCO FP-8300 spectrofluorometer.…”

“…The hemispherical microresonators are made of fluorescent photochromic diarylethenes (DAEs). [22][23][24][25][26][27][28][29][30] Each hemispherical pixel displays WGM photoluminescence (PL), and all the WGM fingerprints are different from one another. The microsphere resonators display WGM luminescence that is switchable upon photoisomerization with UV/visible photoirradiation.…”

Encrypting messages with artificial bacterial receptors

“…In such studies [4][5][6], the emission patterns generated by the probes are used to encode or conceal data [7,8]. One potential advantage of using molecule-based security devices [7][8][9][10][11][12][13][14][15][16][17][18][19] over conventional electronic security systems is that the former cannot be subjected to electronic surveillance [4][5][6]. The small scale, versatility, and unusual operating principles are additional properties that significantly complicate finding and breaking into molecular security systems.…”
