A firefly inspired one-pot chemiluminescence system using n-propylphosphonic anhydride (T3P)

Abstract

A simple reaction procedure for chemiluminescence of firefly luciferin (D-luc) using n-propylphosphonic anhydride (T3P) is reported. A luminescent photon is produced as a result of one-pot reaction, only requiring mixing with the substrate carboxylic acid and T3P in the presence of a mild organic base.

Boosted Responsivity and Tunable Spectral Response in B‐Site Substituted 2D Ca2Nb3−xTaxO10 Perovskite Photodetectors

“…The TaO bond is less covalent than that of the NbO bond, and the bond angle of BOB is also influenced. [ 43 ] Therefore, the substitution of Ta might introduce the distortion of BO 6 octahedra in the Ca 2 Nb 3− x Ta x O 10 crystal, [ 28,31 ] coincident with the peak shifts in XRD patterns. Moreover, although Ta and Nb atoms own the same number of valance electrons, the electronegativity difference between them would possibly introduce an in‐gap defect level, and the lower electronegativity of Ta atom ( X Nb = 1.6, X Ta = 1.5) endows it with the capability of trapping holes.…”

“…Considering the same ionic radius of Nb 5+ and Ta 5+ (0.64 Å), Ta may substitute Nb to occupy the B‐site in the perovskite slabs. [ 27,30,31 ] Figure 2c–f displays a transmission microscopy (TEM) image, a high‐resolution TEM image (HRTEM), selected area electron diffraction (SAED) pattern, and element mapping images for the Ca 2 Nb 2.5 Ta 0.5 O 10 nanosheets, respectively. The TEM image (Figure 2c) further illustrates the morphology of the materials, the 2D objects with the lateral size of ≈ 1 µm are identified as nanosheets.…”

Ring-Fused Firefly Luciferins: Expanded Palette of Near-Infrared Emitting Bioluminescent Substrates

“…Firefly luciferin is known to glow chemiluminescence induced by npropylphosphonic anhydride (T3P) and triethyl amine (TEA) in DMF. 32 This nonenzymatic light production involves the formation of an activated acyl-phosphonic acid intermediate followed by oxidative reaction, which mimics the luciferase catalyzed bioluminescence reaction (Figure 2A). Once T3P was added into luciferin solutions, robust light emission was observed from all synthesized analogues.…”

“…With the synthesized analogues in hand, we first evaluated the light emitting potential of the synthetic luciferins. Firefly luciferin is known to glow chemiluminescence induced by n -propylphosphonic anhydride (T3P) and triethyl amine (TEA) in DMF . This nonenzymatic light production involves the formation of an activated acyl-phosphonic acid intermediate followed by oxidative reaction, which mimics the luciferase catalyzed bioluminescence reaction (Figure A).…”

A New Generation Co‐Assembled Small Molecular Gel with Polyaniline: Exciting Mechanical, Electronic and Photovoltaic Properties

“…They find plethora of applications in fuel cells, super capacitors, dye sensitized solar cells and rechargeable lithium batteries. [6][7][8][9][10] Conductive gels are engineered by adding conductive particles to the gel matrix, [11] preparing the gels from conducting polymers [12][13][14] or introducing conducting polymers into the network structure of the gels. [15,16] They are also synthesized via blending, doublenetwork (DN) and triple network (TN) formation, [17][18][19][20] although it is reported that the blending method mitigates the mechanical properties of the conducting composite gels.…”
