“…The best-established systems of SAMs are those of alkanethiolates on Au (67) and Ag (68), and alkylsiloxanes on hydroxyl-terminated surfaces such as Si/SiO 2 , Al/Al 2 O 3 , glass, mica, and plasma-treated polymers (60,69,70). Less-well-characterized systems of SAMs include alkyl groups directly bound to Si (71,72); alkanethiolates on Cu (73), GaAs (74), and InP (75); alkanesulfinates (76) and alkylphosphines (77) on Au; alkanethiolates on Pd (78); alkylisonitriles on Pt (79); carboxylic (80) and hydroxamic (81) acids on metal oxides; alkylphosphates on ZrO 2 (82); and alkylphosphonic acids on In 2 O 3 /SnO 2 (ITO) (62).…”

Elastomeric stamps and molds provide a great opportunity to eliminate some of the disadvantages of photolithograpy, which is currently the leading technology for fabricating small structures. In the case of "soft lithography" there is no need for complex laboratory facilities and high-energy radiation. Therefore, this process is simple, inexpensive, and accessible even to molecular chemists. The current state of development in this promising area of research is presented here.

“…Different SAM molecules have been used, depending on the metal. For example, alkanethiols have been used for gold (Delamarche, 1996), silver (Fenter, 1991), copper (Schlenoff, 1995), and palladium (Lee, 1991); alkanephosphonic acids for aluminum (Goetting, 1999); alkylisonitriles for platinum (Hickman, 1992); carboxylic acids for metal oxides (Tao, 1993); and alkanesulfinates (Chadwick, 1993) and alkylphosphines (Uvdal, 1995) for gold patterning. Typically, the inked polymer stamp is in contact with the metal film for only a short time because the SAM is formed quickly upon contact (Larsen, 1997).…”

Metallic nanostructures now play an important role in many applications. In particular, for the emerging fields of plasmonics and nanophotonics, the ability to engineer metals on nanometric scales allows the development of new devices and the study of exciting physics. This review focuses on top-down nanofabrication techniques for engineering metallic nanostructures, along with computational and experimental characterization techniques. A variety of current and emerging applications are also covered.

“…Such a result is in agreement with studies made on benezenethiol SAMs on gold, albeit that the investigations took place over only a 10 day period. 46,47 Evanescent wave excited ¯uorescence emission spectra from the SAM of 1 were recorded and analysed over a period of 24 months. Over the 24 month time period the ¯uorescence intensity and emission pro®le of the SAM of 1 were unchanged from that shown in Fig.…”

A series of three Phthalocyanine (Pc) derivatives have been designed, synthesised and formulated as selfassembled monolayers (SAMs) on gold-coated optical waveguides. The alkyl chain tethering the Pc macrocycles to the gold surface via a thiol moiety varied in length viz. (CH 2 ) 11 , (CH 2 ) 8 and (CH 2 ) 3 . The three Pc SAMs have been characterised using re¯ection absorption infrared spectroscopy and ¯uorescence spectroscopy excited via the evanescent wave. The infrared data have shown that the length of the alkyl tether has a profound effect on the orientation and packing density of the Pc macrocycle on the gold surface. Similarly, the intensity of ¯uorescence observed from the Pc monolayers was related to the length of the alkyl tether. A further investigation of the C 11 Pc derivative SAM has shown that the monolayer ®lm was stable, exhibiting no oxidation and only minor orientation changes on the gold surface over a period of 24 months as determined by infrared and ¯uorescence spectroscopy. The longevity of the Pc SAM is thought to be due to the macrocyclic ring possibly preventing oxidation of the thiolate root. As simple alkanethiols are known to oxidise at gold surfaces, the stability results obtained for the Pc derivative would suggest that macrocyclic SAMs may have properties that are more suitable for long term applications.
