(Pro2H+)2(TCNQ.−)2⋅TCNQ: An Amino Acid Derived Semiconductor

Abstract: An attractive couple: (Pro2H+)2(TCNQ.−)2⋅TCNQ (TCNQ=tetracyanoquinodimethane) contains an H‐bonding network that supports a layered structure, composed of alternating TCNQ anions and proline cations (see picture). The cation is formed by two zwitterionic proline amino acids supported by a proton bridge between the carboxylates, whereas the anionic component involves a neutral TCNQ molecule sandwiched between two TCNQ.−.

“…Furthermore, it is evident from the I-V curves that the material 3 is highly conductive compared to material 2 in the applied bias range. [14,20,21] This clearly demonstrates the efficacy of supramolecular material exhibiting photochromic behavior with high charge mobility, which is attractive for a highly sensitive organic semiconducting material. The values of R for the samples 2 and 3 were obtained from the linear region of I-V curves in the bias range of AE 0.12.…”

“…[19] It may be noted that these values are higher than those of well-established conjugated polymers and other single-crystalline organic semiconductors.

“…The Raman spectrum of LiTCNQ‐TiO 2 (red spectrum) presented the peaks observed in raw materials used to fabricate the composite. In addition, the peak at 1387 cm −1 which is consistent with the presence of TCNQ .− species splits to give two peaks at 1375 cm −1 and 1387 cm −1 due to the interaction between TiO 2 particles and LiTCNQ molecules.…”

“…[4][5][6][7][8][9][10][11] Copper derivatives have recently demonstrated practical applications,a si llustrated by their super-hydrophobicity. [12,13] In contrast, studies of the TCNQF 4 2À dianion with metal or organic cations are limited because the TCNQF 4 2À dianion is less stable than that of the TCNQF 4 1À monoanion in solution.…”
