Organoarsenic chemistry was actively studied until the middle of 20th century. Although various properties of organoarsenic compounds have been computationally predicted, for example, frontier orbital levels, aromaticity, and inversion energies, serious concern to the danger of their synthetic processes has restricted experimental studies. Conventional synthetic routes require volatile and toxic arsenic precursors. Recently, nonvolatile intermediate transformation (NIT) methods have been developed to safely access functional organoarsenic compounds. Important intermediates in the NIT methods are cyclooligoarsines, which are prepared from nonvolatile inorganic precursors. In particular, the new approach has realized experimental studies on conjugated arsenic compounds: arsole derivatives. The elucidation of their intrinsic properties has triggered studies on functional organoarsenic chemistry. As a result, various kinds of arsenic-containing π-conjugated molecules and polymers have been reported for the last few years. In this minireview, progress of this recently invigorated field is overviewed.

Methanol-Triggered Turn-On-Type Photoluminescence in l-Cysteinato Palladium(II) and Platinum(II) Complexes Supported by a Bis(diphenylphosphine) Ligand

et al. 2016

The selective detection of methanol by photoluminescence under environmental conditions has been a great challenge for materials science. Herein, a reversible, turn-on-type photoluminescence triggered by methanol vapor in square-planar palladium(II) and platinum(II) complexes, newly prepared from [MCl2(1,3-bis(diphenylphosphino)propane)] and L-cysteine, is reported. Both the "turn-on" and "turn-off" states of the complexes were crystallographically characterized, which revealed the presence of intermolecular OH···O and CH···π interactions between methanol and the complex molecules in the turn-on state. These interactions prevent the vibrational quenching of the luminescence, leading to the turn-on-type luminescence in this system.

“…Chemical sensors (chemosensors) of VOCs making use of the optical properties displayed by photoluminescent material have been extensively studied [6][7][8][9][10][11]. In this case, the detection relies on luminescent properties of chemosensors upon interaction with any analytes.…”

“…For example, group 11 metal (Cu, Ag, Au) complexes can provide phosphorescent properties with strong emission and bright color in the visible spectrum that are highly required for better evaluation of sensing capability [12][13][14][15][16][17][18][19][20]. Comparing to platinum and palladium as well as their double salt complexes [6,7,21], these compounds can be synthesized from a cheaper precursor with higher yields. Indeed, gold(I) complexes have better stability compared to copper(I) and silver(I) complexes due to its correlation and relativistic effect [12][13][14][15]22].…”

Systematic Study on Sensing Capability of Gold(I) Pyrazolate Complex for Vapochromic Chemosensors of Ethanol Vapors

Modified gold complexes as dinuclear adducts with silver bridge ions, clusters with other metal ions, and bimetallic sandwiches have shown better sensing capabilities for vapochromic chemosensing of organic vapors than its unmodified structure. Herein, a simple gold(I) complex, synthesized from 4-(3,5-dimethoxybenzyl)-3,5-dimethyl pyrazole ligand, have been shown to have higher sensing capability toward ethanol (EtOH) vapors. Such sensing capability can be possibly achieved when EtOH vapors have enough time to diffuse to the main sensing sites of the sensor. Thus, 80 to 160 µL (with 20 µL increment) of EtOH vapors were exposed to the synthesized gold(I) pyrazolate complex at varied distances of 2.75, 11 and 22 cm for 15 minutes. The complex displayed its sensing capability by quenching at its emission intensity of 600 nm up to 80%, which suggests the possible interaction of the EtOH vapors with the inner sensing site originated from the Au(I)–Au(I) interaction of the complex where it is possible to breakdown the light-emitting capability. Prior to this interaction, there was only a slight blue-shifting of 9 nm away from its emission intensity by the binding of EtOH vapors to the methoxy of benzene ring hence only demonstrating weak sensing capability. These results indicated that sensing capability as shown by the quenching phenomenon at the emission intensity of gold(I) complex is dependent on diffusion time of EtOH vapors.
