This work indicates that the photovoltaic response is closely correlated with the substituents. The molecular structure/photovoltaic response relationship is presented and discussed in terms of the charge separation in an intramolecular charge transfer compound.展开更多

The recognition pattern was found that each barbituric(or melamine) group forms 9-fold H-bonds on its two edges, respectively, with two of its neighboring melamine(barbituric) cores in the ratio of 1:1 on air-water interface. The area per molecule in this pattern is about 60-65 Angstrom(2) for both B1 and B2. Such recognition improves the monolayer formation of B1 by increasing the collapse pressure around 20 mN/M and modulates the intermolecular distance of B2 in monolayer. These effects should be quite meaningful for both theoretical research and practical application of Langmuir-Blodgett films, especially.展开更多
