The title complex, C17H9N5*C6H4S4, contains pi-deficient bis(dinitrile) and TTF molecules stacked alternately in columns along the a-axis direction; the interplanar angle between the TTF molecule and the isoindolinyl C4N[C(CN)2]2 moiety is 1.21 (4) degrees. The N-allyl moiety in the TCPI molecule is oriented at an angle of 87.10 (10) degrees with respect to the five-membered C4N ring, and the f...

In the title compound, C(26)H(21)N(3)O(3)S, the quinazolinyl group is essentially planar [r.m.s. deviation for the 10 non-H atoms = 0.057 Å]. The isoindoline-1,3-dione group is linked by an SCH(2)CH(2) chain to the pyrimidinyl C atom that lies between the two N atoms. Also, the phenyl group is linked by a CH(2)CH(2) chain at the N atom adjacent to the carbonyl group. This results in a conformat...

松下 亨 The present investigation was performed in order to clarify the mechanism of ataxic behavior following the administration of 2-(3-dimethylaminopropyl)-1,3,3a,4,9,9a-hexa hydro-4,9-o-benzeno-2H-benz[f]isoindole dimethiodide (MI-65-S) to mammals. For several years, many bis-quaternary ammonium salts containing a bicyclo(2.2.2) octane ring in their large cationic head have been synthesized in...

Recently, more and more rhodamine derivatives have been used as fluorophores to construct sensors due to their excellent spectroscopic properties. A rhodamine-based fluorescent and colorimetric Fe(3+) chemosensor 3',6'-bis(ethylamino)-2-acetoxyl-2',7'-dimethyl-spiro[1H-isoindole-1,9'-[9H]xanthen]-3(2H)-one (RAE) was designed and synthesized. Upon the addition of Fe(3+), the dramatic enhancement...
