Abstract:
An asymmetric, amphiphilic perylene bisimide derivative 1 was synthesized by grafting permethyl-β-cyclodextrin at one side and an octadecyl chain at the other side. Its aggregation capability and morphology, which attract intense interest, were carefully examined by combination of UV-vis, NMR, and fluorescence spectroscopy, DLS, XRD, TEM, and SEM. By adjusting the volume ratio of water and methanol, we are able to control the morphology, benefiting from the amphiphilicity of 1. Furthermore, the particular resulting aggregates were employed as solid-state fluorescence sensing for organic amines. An improvement of both selectivity and sensitivity is achieved compared to previous publications.

Conjugated Proteins
Nucleoproteins are protein complexes that contain nucleic acids, categorized as deoxyribonucleoproteins (DNPs) or ribonucleoproteins (RNPs) respectively. The nucleosome is a typical example of a DNP where nuclear DNA is associated with histone proteins. The major antigen for the Covid-19 virus SARS-CoV is an RNP that is critical...
