• . We discuss some recent studies based on X-ray photoelectron spectroscopy that shed light on these aspects for a series of such organic molecules. Keywords: copper; nickel; palladium; reactivity; selenol; selenophene; self-assembly; thiol; thiophene; Introduction In recent years research related to

• molecules that have been extensively studied on Au and a few aromatic molecules such as benzenedithiol, thiophene derivatives and selenophene that are of interest in molecular electronics. Experimental The experimental procedure has been outlined in detail in previous publications [22][23][24][26][27][43

• selenophene were purchased from Sigma-Aldrich and α,ω-dihexylquaterthiophene (DH4T) from SYNCOM, and all were used as supplied. DC6DSe ((CH3CH2)5Se)2 was synthesized according to the procedure described in an earlier publication [43] and in Supporting Information File 1. Adsorption of DC6DSe was performed
