Multi-stimuli programmable FRET based RGB absorbing antennae towards ratiometric temperature, pH and multiple metal ion sensing

Abstract

RGB antennae consisting of naphthalimides, perylenediimides and aza-BODIPY with efficient FRET show unique ratiometric temperature sensing, metal sensing (FRET-off) and pH sensing through various stimuli sensitive band tuning.

Dual Stimuli-Responsive BSA-Protected Silver Nanocluster-Driven “FRET On–Off” within the Niosomal Membrane: An Amalgamation of Restoration of Aggregation-Induced Quenched Fluorescence and Energy Transfer

“…Thus, the BSA@AgNCs would find a stable residence inside the niosomal membrane. There are plenty of works on the stimuli-responsive behavior of FRET pairs in preparing luminescent thermometers as well as several other ratiometric sensing applications in vivo and in vitro . , Some of the works reflected the multiple stimuli-responsive behavior in lipid membranes and polymeric phases. − These reports are principally based on the photophysical parametric changes due to phase transition. There is a single report on stimuli-responsive reverse FRET in emissive Pt­(II) cages in a bulk solvent medium .…”

Unravelling the excited state dynamics of monofunctionalized mono- and distyryl-BODIPY and perylenediimide dyads

“…Accordingly, a large class of multichromophoric donor-acceptor systems have been designed and their dynamics of energy/electron transfer have been probed in the context of biomimetic photosynthetic systems and also optoelectronic applications. [9][10][11][12] BODIPY dyes with their synthetic versatility, high absorption coefficient, absorption in the visible region (350-650 nm), thermal and photochemical stability and high charge carrier mobility are ideal candidates for artificial LH systems. 13 The efficiency of light-harvesting can be enhanced by harnessing excitonic coupling among the chromophores, which has been recently reported for cyclic BODIPY derivatives.…”

On the Use of Polymer-Based Composites for the Creation of Optical Sensors: A Review

“…There are many polar substituents that contribute to the formation of dipole interactions with the corresponding substrates. Such matrices include: among the organic ones most popular are oligo-polysaccharides [ 46 , 47 ], cellulose [ 48 , 49 , 50 , 51 ], polymethylmethacrylate (PMMA) [ 52 , 53 , 54 , 55 ], polyvinyl chloride (PVC) [ 11 , 56 ]; among inorganic ones most popular are silica and other polymeric oxides obtained by sol-gel synthesis [ 57 , 58 , 59 , 60 , 61 , 62 ]. On the other hand, the luminophore must have the following groups (one or several): H-, hydroxo-, amino-, nitro-, sulpho-, mercapto- and groups comprising from atoms with an unsplit electron pair and capable of forming a donor-acceptor bond; phenyl and other cyclically conjugated molecules to form π-π stacking.…”
