Two electron donor-π-acceptor (D-π-A) chromospheres, with ferrocene as the electron donor and pyridinium as the electron acceptor, were synthesized. The nonlinear optical absorption (NOA) properties in the solution state were investigated by the Z-scan technique. Both compounds exhibited reverse saturable absorption (RSA) and optical limiting effect under nanosecond pulse irradiation.

First anion···π contacts with quinoid rings have been described in novel co-crystals of tetrabromo- and tetrachloroquinone with iodide salts of substituted N-methylpyridinium cations. In seven crystal structures of these co-crystals, a centrosymmetric unit I-···quinone···I- is observed involving close contacts between iodide anions and electron-depleted carbon skeletons of the quinoid rings. However, the salt with N-methyl-4-methylcarboxypyridinium base crystallizes in two polymorphs characterized by O=C···quinone···C=O interaction instead of I-···quinone···I- one. A possible charge transfer, suggested by the black color of the crystals, is probed by solid-state NMR and IR spectroscopies and analyzed by DFT calculations.

The probe can be used for detecting G - quadruplex structures. in a solution through a fluorescence spectrophotometer, and the probe can be used for detecting a (I) quadruplex structure, in a nucleic acid, quadruplex structure, and has good cell membrane
Combinatorial approach to organelle-targeted fluorescent library based on the styryl scaffold
Rosania, Gustavo R.,Lee, Jae Wook,Ding, Liang,Yoon, Hai-Shin,Chang, Young-Tae
, p. 1130 - 1131 (2007/10/03)
The first fluorescent styryl dye library with a broad color range was synthesized by combinatorial condensation of various aldehydes and methyl pyridinium compounds, and their applications as organelle specific staining probes were demonstrated. Copyright
GEAR EFFECT-10 CONFORMATIONAL ASPECTS OF THE POSITIVE OR NEGATIVE BUTTRESSING EFFECTS OF METHYL GROUPS: POLYMETHYLPYRIDINES
Roussel, Christian,Balaban, Alexandru T.,Berg, Ulf,Chanon, Michel,Gallo, Roger,et al.
, p. 4209 - 4220 (2007/10/02)
The effects of the shape of a methyl group on reactivity, which cannot be accounted for by considering a methyl group as a spherical subtituent with the appropriate van der Waals radius, was considered in kinetics of alkylation of substituted pyridines and barriers to rotation and ground state conformations of an isopropyl group attached to a planar framework.The perturbation of a methyl group by an o-methyl group is accounted for by a unique conformational explanation which involves the polyhedral shape of the methyl group.
