These compounds showed the activities of anti-HSV-I. The structure of 1 was determined by spectral analysis.展开更多

Results of CV experiments show thatthere are no structUral defects exposed directly to the redox couple in solution, but EISexperiments indicate that collapsed sites exist in the monolayer. A method to estimate the degree ofdisorder in the Au/thiol monolayer surface is proposed by using admittance plane plot.展开更多
The coaggregating tendencies of five methyl esters of saturated or unsaturated single-chain carboxylic acids, namely octanoic (8-Me), dodecanoic (12-Me), stearic (18-Me), oleic (c18:1-Me) and elaidic (t-18:1-Me) acids...The coaggregating tendencies of five methyl esters of saturated or unsaturated single-chain carboxylic acids, namely octanoic (8-Me), dodecanoic (12-Me), stearic (18-Me), oleic (c18:1-Me) and elaidic (t-18:1-Me) acids, were investigated in five aquiorgano binary solvent systems, V/V DX-H2O (Phi=0.50, 0.45, 0.40, 0.30, 0.20), using naphthylethyl octyl (Np-8), dodecyl (Np-12), hexadecyl (Np-16) ether as fluorescent probes. The orders of their coaggregating tendencies changed in solvents of different Phi values. Our results could be rationalized by a chain-foldability effect without neighboring moiety participation.展开更多
