In this Letter, we characterize the vibrational levels of 1,2,4,5-tetracyanobenzene (TCNB) in the electronic ground and first excited states by dispersed fluorescence and laser induced fluorescence spectroscopy. The Franck–Condon activity was observed in the totally symmetric modes 6a, 9a, 1, ...
A new charge transfer cocrystal of 1,2,4,5-tetracyanobenzene(TCNB)-phenazine(PTC)was prepared by solvent evaporation method.The donor and acceptor molecules of cocrystal are stacked face to face with a mixed-stacking,implying a strong charge transfer(CT)interactions in the cocrystal system.The ...
The absorption spectrum of poly(vinyl alcohol) (PVA) film doped with 1,2,4,5-tetracyanobenzene (TCNB) was measured after the irradiation with several hundred MeV of C, Ne and Ar ions. The absorbance due to the TCNB radical anion increased and then decreased with increasing the fluence for...
Herein, using 1,2,4,5-tetracyanobenzene (TCNB) as electron acceptor, carbazole (CARB), dibenzothiophene (DBZP) and dibenzofuran (DBZF) as electron donors, three charge transfer cocrystals of CARB-TCNB, DBZP-TCNB and DBZF-TCNB were synthesized by solvent evaporation method and solvent-assisted...
The new complexes [(4,η4-TCNX){Os(PR3)2(CO)(H)Cl}4], R=isopropyl, TCNX=tetracyanoquinodimethane [TCNQ, 2,2′-(cyclohexa-2,5-diene-1,4-diylidene)bis(propane-1,3-dinitrile)] or 1,2,4,5-tetracyanobenzene (TCNB), were studied by spectroelectrochemistry in the UV/VIS/NIR and...
