Keywords: organic thin films; selenolates; self-assembled monolayers; thiolates; triptycene; Introduction For more than three decades now, self-assembled monolayers (SAMs) have enjoyed ever-increasing popularity in the modification and functionalization of surfaces. Numerous applications of SAMs have been

Recently, it has been shown that the growth of HKUST-1 on –COOH-terminated triptycene (Trp)-based SAMs proceeds along a different crystallographic axis than the growth on SAMs with a higher surface density of –COOH-functions, indicating that the surface density of –COOH

For this reason, we aimed to systematically investigate how the structure, stability and the order of monolayers of molecules with the highly space-demanding triptycene moiety depend on the anchor group (thiolate vs selenolate) and how they are influenced by the presence or

• time we report the construction and subsequent self-assembly of DNA–organic hybrid using triptycene as the organic molecule that allows for the definite disposition of the DNA strands in three dimensions. Triptycene is an interesting molecule having D3h symmetry with Y-shaped structure. It has

• attracted considerable attention in nanotechnology due some of its unique physical and chemical properties [28][29]. Materials derived from triptycene usually exhibit a large surface area with high pore volumes due to the internal free volume (IFV) of the triptycene skeleton. It provides a rigid contortion

• in aqueous media. This limitation could be overcome by functionalization of triptycene molecules with materials having excellent water solubility and functional properties such as DNA. The non-covalent interaction of triptycene derivatives with DNA has been investigated [32][33][34][35]. However, the
