Abstract
Langmuir-Blodgett films of three very similar molecules, BBDAP-C-HETCN Q (1), BDDAP-C-HPTCNQ (2), and BDDAP-C-HBTCNQ (3) were studied by STM and TEM. The areas per molecule and the STM resolution decrease in the order 1 to 2 to 3: it seems that disorder increases, and that a trivi al change in the sigma bridge linking the medium electron donor BDDAP to the strong electron acceptor TCNQ in these three molecules causes m ajor changes in the films.
