Single molecule spectroscopy: (a) and (b) show confocal scan images with dimensions of (20 × 20) µm ² of the 0.7 nm rigid clamp structures and azobenzene-clamped bichromophore respectively. From these images, we extract spot densities of (0.176 ± 0.008) µm ⁻² and (0.011 ± 0.004) µm ⁻² , respectively. (c) and (d) show examples of single-molecule PL decays (black) together with monoexponential fits (red lines).

An azo-clamped nanoscale bichromophoric cyclophane is synthesized by the intramolecular Pd(II)-catalyzed coupling of the corresponding bisacetylenic precursor. The two azo moieties in the latter can adopt cis and trans configurations. Thin layer chromatography shows only two spots, and by scanning tunneling microscopy the trans/trans and cis/cis is...

Herein, we introduced the versatility of free-base and zinc-metallated porphyrin (H2P and ZnP, respectively) to combine with boron azadipyrromethene (azaBDP) NIR absorbing species, for extending their photophysical interest and covalently anchored onto graphene. In particular, the covalent functionalization of graphene with those H2P-azaBDP and ZnP...
