Control of the molecular density in a chemically adsorbed thiophene system monolayer

Control of the molecular density in a chemically adsorbed thiophene system monolayer

Chemically absorbed monolayers (CAM) of thienyl functionalized n-alkyltrichlorosilane 11-(3-thienyl) undecyltrichlorosilane (TUTS) have been prepared with two methods which are the standard technique (TUTS-STD) and the twice adsorption method (TUTS-TAM). The existence of TUTS-CAM was confirmed with...
