Naked-eye chromogenic and fluorogenic chemosensor for mercury (II) ion based on substituted distyryl BODIPY complex

Photophysics of BODIPY Dyes: Recent Advances

“…Due to these excellent photophysical characteristics, BODIPY dyes increase their potential using in different applications such as fluorescent labels for biomolecules and cellular imaging [11][12][13][14][15], light-emitting devices [16][17][18], drug delivery agents [19][20][21], photosensitizers [22][23][24], fluorescent switches [25], chemosensors [26][27][28][29], energy transfer cassettes [30][31][32][33], and solar cells [34][35][36][37]. In this chapter, general photophysical properties of BODIPY and aza-BODIPY derivatives and recent studies on the photophysical properties of these dyes are presented.…”

A molecular design towards sulfonyl aza-BODIPY based NIR fluorescent and colorimetric probe for selective cysteine detection

“…BDP-OH exhibits the emission peak at 731 nm with a uorescence quantum yield (F F ) of 2.58% due to strong ICT effect, which originated electron transfer from two -OH groups to aza-BODIPY core. [22][23][24] The BDP-1-BDP-3 exhibits an emission peak at about 685 nm with a F F value of 0.46-3.30% (in THF) owing to emission inhibition from strong sulfonyl acceptors (Table 1). These uorescence quantum yields were signicantly lower than that of aza-BODIPY core (F F ¼ 34%).…”

Sulu Çözeltilerde Hg2+ Tespiti için Sinnamaldehit Türevi Bir Kolorimetrik Sensör

“…The sensor SAR, combining a cinnamaldehyde moiety (chromophore) and a Hg 2+ receptor moiety formed by a nitrogen motif was designed for a colorimetric sensor for Hg 2+ . It is expected that there would be appearance intramolecular charge-transfer (ICT) (Xue et al, 2019;Aydin and Keles, 2020) between SAR and Hg 2+ with following a significant color change and spectral change. The sensor, SAR, was synthesized in a one-step procedure (Scheme 1) and the sensor was characterized by mass spectrometry, 13 C NMR, and 1 H NMR.…”
