“…This is mainly due to its color-transition property when subjected to external stimuli such as heat, mechanical stress, biomolecules, alcohols, surfactants and other chemicals, rendering it to be utilized in sensing technology [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. To realize its full potential, large amount of works have been carried out, seeking for method to manipulate the color-transition property of PDA.…”

“…For PDA-based chemo/bio sensor systems, the implementation of the sensing mechanism may not require optical and fluorescence imaging with a superior spatial resolution. [45][46][47][48][49][50][51][52][53][54][55][56][57][58][59][60] However, for failure analysis or temperature monitoring systems, heat-induced local fluorescence intensity fluctuations should be characterized on the micro/nanoscale. The size and to some extent, aggregation tendency of the PCDA vesicles within the PVA host matrix are expected to show great influence on the reliability and susceptibility of the composite film.…”

It is shown that due to the inherent irreversible non‐fluorescence to fluorescence transition feature of polydiacetylene (PDA) supramolecules that occurs in response to thermal perturbations, PDA vesicles embedded in a host polymer matrix function as nano/microscale temperature indicators. As a result, they are used to monitor temperature gradients on an integrated circuit chip and to uncover submicrometer size filamentary defects in a resistance random access memory (RRAM) device structure. This new methodology should find a wide applicability in carrying out temperature distribution analysis on semiconductor and micro‐electromechanical system (MEMS) devices where the detection of local heat deviations of small‐scale components is critical. magnified image

“…[20,21] An alternative strategy is the development of supramolecular systems for detecting surfactants by colorimetric and/or fluorimetric methods. [22][23][24][25] We postulated that a colorimetric and fluorimetric supramolecular system for the detection of surfactants could be developed using a hydrophobic rhodamine dye. [26][27][28] A survey of the scientific literature revealed that there are few studies on rhodamine derivatives in micellar media.…”

A rhodamine B derivative appended with a hexyl chain has been synthesized as a colorimetric and fluorimetric probe and studied in three different micelles, sodium dodecyl sulfate (SDS), Triton X-100, and cetyltrimethylammonium chloride (CTAC) in 1:4 (v/v) methanol/water solutions. UV/vis and fluorescence spectroscopic studies suggest that the hydrophobic hexyl chain anchors the probe in the vicinity of the water/membrane interface rather than in the bulk solution. A significant pK a shift of 4.5 units is observed in CTAC and Triton X-100 relative to aqueous methanol solution, whereas no significant difference is observed in SDS. In CTAC and basic solution a nine-fold decrease in the fluorescence intensity and absorbance are observed. These observations are rationalized by a spiro-ring-closing mechanism via lactam formation, which disrupts the conjugated xanthene chromophore. A three-input inverted enabled OR (iEnOR) logic circuit is demonstrated in absorbance and fluorescence mode with CTAC, Triton X-100 and alkali as the inputs via supramolecular assembly.[a] M. Figure 3. Fluorescence spectra of 1 (1.5 mm) in methanol/water (1:4 v/v) excited at 520 nm under the eight experimental input conditions for iEnOR logic at 588 nm.
