• alkyl-radical-derived thin films are resistant toward oxidation, chemical treatment, heating, and mechanical force. The most popular method for the deposition of radical-derived films involves the electrografting of arenediazonium salts [1][2][6][7][8][9][10][11][12][13][14][17][18][19][20]. An

• polyphenylene multilayers. Other methods for aryl radical grafting include electrografting of diaryliodonium salts [15][16], and dimethoxybenzene- or [Ru(bpy)3]2+-photosensitized conversion of arenediazonium salts to aryl radicals in the presence of metal and polymer surfaces [17][18][19][20]. As such

• , arenediazonium salts are workhorses for the growth of aryl radical-derived thin films with broad applications. In stark contrast, alkyl radical-derived thin film growth has received much less attention but is attractive given the broad utility of alkyl and alkyl-containing films [3][4][5][21][22][23][24][25][26
