Abstract:
U sing w et chem ica l reaction betw een 1, 4pieny lened iam ine ( PDA ) and C lte rm ina ted silicon surface, w e present a new and simp le route to d irec tly bond conjugated organ icm o lecu les on silicon surface. The cova lent bond betw een PDA and silicon su rface was charac terized by contact ang lem easurem ent, XPS and AFM, respective ly. A data encom passing exp lanation for them echanism d iscusses the possib le route of the reaction. This simp le and lowcostly re- ac tion o ffers an attractive route to attach functional con jug ated m o lecules onto the sem iconductor surface wh ich a im s to creat som e new mo lecu lar dev ice in the future.
