“…[ 92 ] The third order NLO values were compared with other crystals in Table 7 . [ 49,94–98 ] The third order NLO susceptibility ( χ 3 ) value is high when compared with the KDP crystal. The IHF crystal may be a useful material for photonic device fabrication, third harmonic generation (THG), and optical switch‐making applications.…”

Organic imidazolium hydrogen fumarate (IHF) crystals are grown using the slow evaporation method. The IHF has triclinic crystal structure. The 1H NMR spectrum has five chemical shifts for the IHF crystal. The band at 3155 cm−1 in IR occurs due to the presence of O─H stretching vibration of the IHF molecule. The bandgap value of the IHF crystal is determined to be 4.6 eV. The intense violet emission band is noted at 361 nm. The IHF crystal has thermal stability value of 179 °C. Hirshfeld surface is used to find out the different intermolecular interactions of the IHF crystal. The HOMO–LUMO energy gap is determined to be 4.70 eV. The hydrogen atoms have positive potential in the MEP analysis. The high stabilization energy of 56.81 kcal mol−1 is noticed for π*(C1─N7) → π*(C2─C3) interaction. The third‐order NLO susceptibility (χ(3)) of the IHF is 2.08934 × 10−9 esu.

“…Electronic transmission mechanisms and photocurrent property of photoconductivity of dipeptides have not been well explored. To date, NPC effects have been reported in a variety of materials ranging from simple low-dimensional nanomaterials (graphene quantum dots, 41 InN nanowire, 42 SnO 2 nanoparticles, 43 and MoS 2 single layer 44 ) to various complex crystal structures (γ-glycine, 45 potassium pentaborate, 46 and KCl-doped sulfamic acid 47 ). The decrease in current was explained by the reduction of carrier density or mobility by light-assisted hot electron trapping and carrier scattering.…”

Inverse photoconductance is an uncommon phenomenon observed in selective low-dimensional materials, in which the electrical conductivity of the materials decreases under light illumination. The unique material property holds great promise for biomedical applications in photodetectors, photoelectric logic gates, and low-power nonvolatile memory, which remains a daunting challenge. Especially, tunable photoconductivity for biocompatible materials is highly desired for interfacing with biological systems but is less explored in organic materials. Here, we report nanofibers self-assembled with cyclo-tyrosine-tyrosine (cyclo-YY) having voltage-regulated inverse photoconductance and photoconductance. The peptide nanofibers can be switched back and forth by a bias voltage for imitating biological sensing in artificial vision and memory devices. A peptide optoelectronic resistive random access memory (PORRAM) device has also been fabricated using the nanofibers that can be electrically switched between long-term and short-term memory. The underlying mechanism of the reversible photoconductance is discussed in this paper. Due to the inherent biocompatibility of peptide materials, the reversible photoconductive nanofibers may have broad applications in sensing and storage for biotic and abiotic interfaces.
