Planar chiral asymmetric naphthalenediimide cyclophanes: synthesis, characterization and tunable FRET properties.

A series of planar chiral asymmetric naphthalenediimide (NDI) cyclophanes () consisting of two different NDIs interlinked by rigid meta-dimethylenebenzene spacers was synthesized. A modular synthetic strategy based on the dichloro cyclophane as common precursor gave a straightforward access to racemic mixtures of the NDI cyclophane dyes . In particular the substitution of both chlorine atoms of...

Observation of multiple vibrational modes in ultrahigh vacuum tip-enhanced Raman spectroscopy combined with molecular-resolution scanning tunneling microscopy.

Multiple vibrational modes have been observed for copper phthalocyanine (CuPc) adlayers on Ag(111) using ultrahigh vacuum (UHV) tip-enhanced Raman spectroscopy (TERS). Several important new experimental features are introduced in this work that significantly advance the state-of-the-art in UHV-TERS. These include (1) concurrent sub-nm molecular resolution STM imaging using Ag tips with laser il...

A new scanning tunneling microscope reactor used for high-pressure and high-temperature catalysis studies.

We present the design and performance of a homebuilt high-pressure and high-temperature reactor equipped with a high-resolution scanning tunneling microscope (STM) for catalytic studies. In this design, the STM body, sample, and tip are placed in a small high pressure reactor ( approximately 19 cm(3)) located within an ultrahigh vacuum (UHV) chamber. A sealable port on the wall of the reactor s...

Tip preparation for usage in an ultra-low temperature UHV scanning tunneling microscope

This work deals with the preparation and characterization of tungsten tips for the use in UHV low-temperature scanning tunneling microscopy and spectroscopy (STM and STS, respectively). These specific environments require in situ facilities for tip conditioning, for further sharpening of the tips, as well as for reliable tip characterization. The implemented conditioning methods include direct ...

Oxygen-induced p(3×1) reconstruction of the W(100) surface

The oxidation of the W(100) surface at elevated temperatures has been studied using room temperature STM and LEED. High exposure of the clean surface to O2 at 1500 K followed by flash-annealing to 2300 K in UHV results in the formation of a novel p(3×1) reconstruction, which is imaged by STM as a missing-row structure on the surface. Upon further annealing in UHV, this surface develops a floret...
