A new dibenzothiophene-based dual-channel chemosensor for cyanide with aggregation induced emission

Based on dibenzothiophene fluorophore, a new colorimetric and fluorescent sensing material 2-(dibenzothiophenyl-4-ethenylidenyl)-1,3-indanedione (DTI) was developed, which was a favorable turn-off fluorescent sensor of monitoring CN– ion at extremely low detection limit (0.14 μM) in 99 % aq. DMSO solution. The response mechanism of DTI towards CN– could put down to nucleophilic attack of cyanide group (CN–) toward the double-bond between the dibenzothiophene and the 1,3-indanedione units, which breaking intramolecular charge transfer (ICT) process. This mechanism was proposed by 1H NMR, Job's titration and DFT calculation, leading to a significant fluorescence attenuation and a visual color change. The absorption and emission experiments demonstrated that it showed highly sensitive, selective and good stability for CN– in DMSO/H2O (1:99, v/v). Moreover, DTI displayed high effectiveness in monitoring the CN– in test strips achieved to conveniently determinate CN– by naked-eye without any instruments.

Synthesis, experimental and theoretical characterization, and field-effect transistor properties of a new class of dibenzothiophene derivatives: From linear to cyclic architectures

We report the synthesis and characterization of a bis-dibenzothiophene cyclic dimer containing bis-ethylene linkages (DBT-CM) and of the corresponding mono-ethylene-linked 'linear' cis- and trans-isomers (cis- and trans-DBT-LM, respectively). The varied molecular architectures lead to notable differences both in terms of the solid-state packing and the molecular electronic and optical properties. X-ray crystallography reveals that the cyclic architecture of DBT-CM leads to a more densely packed stacking configuration that imparts stronger intermolecular electronic coupling for both hole and electron transport amongst adjacent molecules, while characterization of the thin-film morphology and crystallinity uncovers important temperature-dependent properties of the films as a function of the molecular architecture. Moreover, the redox, electronic structure, and optical properties of DBT-CM vary distinctly from those of its linear counterparts. The intramolecular reorganization energies for hole and electron transport for DBT-CM are markedly smaller than the linear counterparts, while the dispersion for the highest valence band (and the intermolecular electronic coupling for hole transport) is the largest for the series. The more favorable molecular packing/morphology characteristics and charge-transport properties (within the Marcus framework) of DBT-CM manifest themselves in thin-film field-effect transistor studies, where a field-effect hole-carrier mobility 0.026 cm2 V-1 s-1 is measured, a value one-order-of-magnitude larger than either linear analog.

One-pot synthesis and UV-Visible absorption studies of novel tricyclic heterocycle tethered Xanthene-1,8-diones

Abstract A series of new tricyclic heterocyclic xanthene-1,8-diones tethered with chromophoric dibenzo [b, d]furan, dibenzo[b, d]thiophene and 9-methyl-9H-carbazoles were synthesized through one-pot condensation of dibenzo[b, d]furan-2-carbaldehyde, dibenzo[b, d] thiophene-2-carbaldehyde and 9-methyl-9H-carbazole-3-carbaldehyde with cyclic 1,3-dicarbonyls in the presence of recyclable PPA-SiO2 catalyst under solvent-free conditions. Further, UV-Visible absorption properties of all the synthesized compounds were investigated in CHCl3, THF and acetonitrile. [Figure not available: see fulltext.]
