- Novel n-channel organic semiconductor based on pyrene-phenazine fused monoimide and bisimides
-
Large π-conjugated pyrene-phenazine monoimide and bisimides were synthesized by imine condensation reaction. These imides form well ordered 1D nanotapes upon self-assembly in solution. Electrochemical and electric conductivity measurement reveal it can be served as an n-channel semiconductor with large charge carrier mobility up to 4.1 cm2 V?1 s?1. Both alkylated imides are highly luminescent, and can be quenched via protonization using trifluoroacetic acid, which could be served as potential colorimetric acid sensors.

- Halonitrophthalimides and Phthalodinitriles Derived from Them
-
Quantum-chemical calculations were used to estimate the reactivity of 4-chloro(bromo)- and 3-chlorophthalimides in nitration. It was found by NMR spectroscopy that 4-chloro(bromo)phathalimides undergo stereoselective nitration to give 4-chloro(bromo)-5-ni

- Synthesis, Saludiuretic, and Antihypertensive Activity of 6,7-Disubstituted 1(2H)- and 3,4-Dihydro-1(2H)-phthalazinones
-
The synthesis of the isomeric series 6-chloro-7-sulfamoyl-and 7-chloro-6-sulfamoyl-1(2H)-phthalazinones (1 and 2) and 6-chloro-7-sulfamoyl- and 7-chloro-6-sulfamoyl-3,4-dihydro-1(2H)-phthalazinones (3 and 4), combining structural features characteristic to furosemide and hydralazine, is described, the mechanism of the formation of 1 and 2 is discussed, and their structure-activities relationships are studied.Preliminary screening in the rat shows that series 1 and 3 exhibit diuretic and saluretic activity similar to that of chlorothiazide with, however, Na+/K+ ratios more favorable than chlorothiazide and furosemide.The compounds of series 2 and 4 are practically inactive.All four series show initial antihypertensive activity lower than that of hydralazine.However, compounds 1a, 1c, and 4a show a higher activity at 8 and/ or 24 h after administration and thus may offer a unique combination of a "loop" diuresis with direct long-acting peripheral vasodilating effects.
