Control of Noise in Chemical and Biochemical Information Processing

“…Supramolecular structures have also been considered as switchable devices for logic operations. [103] Chemical-computing equivalents of standard binary gates, such as AND, [104,105] OR, [106] XOR, [103,107] NOR, [91,93,[108][109][110][111] NAND, [111][112][113] INHIB, [114][115][116][117] XNOR [118,119] have been realized.…”

Insight into the excited-state intramolecular double-proton transfer of the 2,5-bis(benzoxazol-2-yl)thiophene-3,4-diol: one-step or stepwise mechanism?

“…The excitedstate intramolecular proton transfer (ESIPT) attracts much attention particularly due to its dual emission with large Stokes' shift, which leads to its significant applications in molecular probes [5,[13][14][15][16], laser dyes [17][18][19], luminescent materials [20][21][22], chemosensors [23][24][25][26][27][28][29][30][31] and molecular logic gates [32], etc. Hence, the mechanism investigation of ESIPT is of vital importance to design, synthesize and regulate desired luminescent molecules [33][34][35][36][37].…”

Novel 6-(1H-benzo[d]imidazol-2-yl) benzo[a]phenazin-5-ol Derivatives with Dual Emission and Large Stokes Shift Synthesis, Photophysical Properties and Computational Studies

“…The molecules exhibiting ESIPT have been exploited as model systems for the study of the proton transfer reaction dynamics [3,4]. The ESIPT reaction, a fast enol-to-keto or (amine-to-imine) prototropy occurring in the excited states of intramolecularly hydrogen-bonded molecules, has been extensively investigated because of its fundamental interest in photophysical properties and potential applications in luminescent materials [5], photo patterning [6], chemosensors [7], proton transfer laser [8], photo stabilizers [9,10], molecular logic gates [11], molecular probes [12], metal ion sensors [13,14], radiation hard-scintillator counters [15], and organic light emitting devices (OLEDs) [16,17], The ESIPT compounds have also drawn much attention due to their potential applications in optical devices [18,19] that may take advantage of the salient properties of the ESIPT compounds such as the ultra-fast reaction rate and extremely large fluorescence Stokes shift [20] compared to the normal fluorophores such as fluorescein, rhodamine or boron dipyrromethene (BODIPY), coumarin [21][22][23].…”
