Endowing Hydrochromism to Fluorans via Bioinspired Alteration of Molecular Structures and Microenvironments and Expanding Their Potential for Rewritable Paper

“…The three classes of fluoran molecules, such as rhodamine B ( RhB ), one dye black ( ODB ), and fluorescein ( FLu ), that are known as acido- or basochromic dyes have been fully investigated for fluorescent probes or display. − They might be good candidates for obtaining the desired hydrochromism. According to our results and literature reports, the colored isomer of RhB is its preferential configuration in most cases, while ODB prefers its colorless lactone form and transforms to its colored zwitterion form only in strong acid .…”

Water-soluble and adjustable fluorescence copolymers containing a hydrochromic dye: synthesis, characterization and properties

“…Synthesis/preparation of NH 2 -Rh, AM-Rh and Poly(AM-Rh x co NIPAM y )s NH 2 -Rh was prepared according to reported literature. 49 Synthesis of AM-Rh. NH 2 -Rh (1 mmol, 457 mg) was dissolved in CH 2 Cl 2 (10 mL), and Et 3 N (2 mmol, 270 mL) and acryloyl chloride (1.2 mmol, 98 mL) were added dropwise to the solution…”

An AIE fluorescent switch with multi-stimuli responsive properties and applications for quantitatively detecting pH value, sulfite anion and hydrostatic pressure

“…[23][24][25][26] Although they possess high sensitivity, most stimuli-responsive materials can only detect one type of stimulus. 27,28 In order to realize multi-parameter detection in a complicated environment, multistimuli responsive materials are usually fabricated by integration of several different stimuli-responsive moieties into one molecule or by tagging them to polymers, which require tedious and costly construction processes. [29][30][31][32] Fluorescent molecular switches have received great attention as multi-stimuli-responsive materials.…”
